X.org Lockups (part III)

In case this is useful to anyone who ends up here:

I recently experienced a problem that sounds similar to what at least some people here are seeing.

When I tried to start X, the machine would crash hard, - no network response, only way out being the reset button. Completely reproducible.

I needed to add some modules to my kernel configuration. The problem started following a kernel compile and reboot (doesn't happen often).

amd64, xorg-server-1.7.6, nvidia-drivers-190.42-r3, vanilla-sources-2.6.31.6

I tried re emerging nvidia-drivers, that didn't help. Made sure everything was up to date (emerge -uDN world) and no broken reverse dependencies (revdep-rebuild -i), still didn't help.

To cut a long story short, the thing that actually fixed it was to do an: emerge -e xorg-server

I noticed a couple of days ago I went from gcc-4.3.4 to gcc-4.4.3-r2. This is essentially just a guess, but I suspect the problem was caused by having various parts of the system (xorg-server, nvidia-drivers, kernel, various X11 libraries etc) built with the different gcc versions. It could have been a dynamic link library version issue either, but a full rebuild to really ensure everything was consistent seemed to fix it either way. I'm now doing an emerge -e world to try and preemptively fix any other weirdness on the system resulting from similar issues.

I'm having a strange issue for a long time, with different versions of software., maybe anyone can give me a hint:

I'm running KDE4 @ amd64, Core2Duo and 2 GB RAM, overall system seems to work fast and responsive, but on a really intense io operations (building GCC/OpenOffice, huge file processing, loading modern videogame) there is a small chance to get a deadlock (seems to happen only with KDE running, not with icewm). All processes get stalled waiting for disk, not utilizing CPU. Hard disk is raving mad and at same time nothing happens, probably everything stops to work (load is about 30). If I manage to kill X with a magic key (even if heavy io process is running in tty), everything goes back to norm in seconds. If not, system hangs after a while.

I know about the mystic IOWAIT bug, but why it affects only KDE?

Thanks in advance.

Hi all,

on 2.6.34-r1, ThinkPad T410 with Intel Arrandale with a custom kernel
the laptop freezes on startx or X -retro -config /root/xorg.conf.new (with
a fresh created xorg.conf.new with Xorg -config).

as this happens I'm not able to switch the tty, the laptop doesn't respond
to ping and caps lock is constantly blinking.

there is no error in /var/log/Xorg.0.log and Xorg -config exits without
complaining about anything.

I followed the guide at:
http://www.gentoo.org/doc/en/xorg-config.xml#using_startx

so I completed all steps mentioned there.

at this point I have no idea how to debug, get information what is
going an, or what causes the problem - there are no error messages
and no log left. the only thing I see is a black screen, a blinking cursor
at the top left corner for a moment and a completly black screen after wards
and laptop the responds to nothing as a result. the only way that i could
get out of this was to hard-reboot using the power button.

please post here if you have any ideas what this could be or
how can it be figured out what causes the crash.

thanks in advance,
~esiminch

p.s. at this point i'm waiting for emerge -e xorg-server to complete after
i read the post from phirst above (sorry but i didn't see it before i've posted, a strange
sorting of posts, or me not used to phpbb).

pp.ss. still the same situation after emerge -e xorg-server

@ esiminch,
same here..
i've nuked yesterdays install, & installing from a basic stage4.. i'll update as soon as the emerge is done!

tell, is it a clean install? did you change your CFLAGS? is it nvidia VGA? did you emerge -s system/world?

@naelk

yes, it is a clean install, my CFLAGS are:
-O2 -march=i686 -pipe

starting X with vesa works fine and no, i did no emerge -s system/world

good luck:-) i also keep trying, maybe a different kernel version, vanilla maybe
or a different version of gento-sources.

i guess the problem is the the new KMS feature of the kernel, at least the kernel crashes
on startx because with KMS it tries to do the Xorg job (set resolution and the kind).
i did not had the opportunity to test it yet, but I guess that disabling kms
should at least prevent the crash.

http://en.gentoo-wiki.com/wiki/Intel_GMA

by the way, intel seems to be the only chip that supports kms.

another hint i got on the gentoo-desktop list, to try the ~x86 kernel
that may already contain fixes.

I get a lockup on my current machine/config ONLY when xscreensaver is loaded. Before I post a bug report, I thought I'd post here to see if it's just that I missed something. However, I can say that if I load xscreensaver, it X inevitably locks and I can only power off the machine and reboot.

My newly installed 64bit Gentoo has the similar freeze issue.

Each time when I login to gnome, the whole system has quckly after I move the mouse over the menu or open a window.

I don't think it's reason by KMS, I have tried to disable KMS in kernel, and seems no change for the issue.

Hello all,

I think this is the correct thread for this since X freezes up on a new to me computer I have freshly installed Gentoo/AMD64 on. Any insight would be appreciated.

Symptom : Sporatic freezing of X while in Fluxbox and Gnome to a pure white screen. It is very random as to when it does it, it doesn't coincide with any particular application being open or any specific use of opengl or other acceleration. It can occur in as little as 5 minutes once X is loaded, or sometimes a few hours later.

Hardware : Athlon 3500+ on an Mobo from an HP Pavillion with integrated Radeon Express 200 graphics. No expension cards installed, pretty basic board with an Sata, Pata, Floppy, and ECHI/OCHI controllers.

History of attempted 'fixes':
1. Ran memtest86 on the memory, since in the past I have always associated random lockups with bad ram. Turns out I had a bad pair of sticks during the original install. I replaced them with another set and tested the memory again for a few hours, with no errors this time.
2. Did a fresh bootstrap followed by an emerge -e world to get rid of any code that may have had bad bits in it from being compiled and cached in the bad ram.
3. While under full compile load I checked the power supply output voltage and ripple with my Fluke meter, no issues there, everything was right about where it should have been.
4. Installed WinXP 64bit on a second drive to see if it works OK. Windows has no issues and will run for days without a lockup.
5. I disabled all of the onboard components I am not using, i.e. the game, parallel, and serial ports to free up IRQs. I checked in /proc /interrupts and everything seems OK there.
6. Flashed the BIOS to the newest version I could find for the board, which was actually a Gateway BIOS for the same board.

emerge --info

Since the full emptyset emerge has completed I have experience only two lockups in two days of running, once almost immediately after I first rebooted the machine after the emerge completed (Quite frustrating after a day of compiling) and then about 4 hours later while playing eduke. If you leave this machine sitting in a VT it will run for days, only once X is open do I have an issue.

Charles,

Did you find a solution to the same problem as I am having in the preceeding pages?

Nothing there really worked for me, except for trying the KMS driver. Being the ATI and in kernel DRI newb, I didn't even really read into what KMS was, or why the option was there in the kernel. I selected that two days ago, and now I've had the machine up with over 30 hours uptime with X being woken up here and there as I use it, with no glitches. The acceleration is a bit faster too, I have been able to run RTCW at 20-30 fps at 800x600, amazingly. The built-in accelerated frame buffer is nice too. I'll post if I have no more issues after a week.

Cheers,
Shawn

I'd like to update how the KMS driver has been working, and that could be summed up with "flawlessly". It is a much better solution than the original driver package, with a nice native res. framebuffer to boot. The onboard 'card' still sucks at gaming, but I've had uptimes of a month now without video card issues.

Cheers,
Shawn

The last keyboard, mouse and X lock up I had was freed by recompiling all the drivers:

hi, ive got a problem with my xserver

_XSERVTransSocketINETCreateListener: ...SocketCreateListener() failed
_XSERVTransMakeAllCOTSServerListeners: server already running

My xorg is crashing since the last update. I was using kernel 2.6.31, if I remember correctly, with reiser4 patches. Now I'm using zen-sources, as it has reiser4 built-in, and it saves me the trouble.
I'm using ati-drivers, the fglrx binary driver, for my Radeon HD 4850 video board. Sometimes KDE 4 crashes after a couple minutes, sometimes just after starting the xdm init script, which calls kdm. Other times, as soon as I type startx, after removing xdm from the default runlevel, my keyboard and mouse gets unresponsive (keyboard leds don't respond to keypresses), and I get a blank black screen. I can ssh into my box, but I can't even reboot it. The pc just hangs, probably messed BAD the video memory or something.

My revelant info files:
xorg.conf: http://paste.pocoo.org/show/403197/
dmesg after a crash, saved from ssh: http://paste.pocoo.org/show/403198/
kernel .config: http://paste.pocoo.org/show/403199/
Xorg.0.log (from the current, working Gnome DE, but the failing KDE session doesn't change much, couldn't find anything unusual in xorg logs after a crash): http://paste.pocoo.org/show/403200/

When Xorg got upgraded on my last update to 1.12.99.903, it caused anything Mozilla to log the user out. I've determined that Mozilla is not the problem because it does not matter what version of FF or TB I use. What does "fix" it is downgrading Xorg to the previous version (1.12.3). I have put 1.12.99.903 in my package.mask.

Has anyone had difficulties with getting the Gentoo kernel sources newer than 3.10.7 to work with the nouveau kernel driver? I have the following Xorg server and drivers built (no xorg.conf is defined in /etc/X11):

Sorry to continue this post in this way, pasting log files was not working. Xorg.log and xdm.log files contain no errors, although kdm.log did contain a cryptic message about not finding a dbus session to connect to, despite dbus starting and running OK. OpenGL is implemented and selected:

Since a couple of weeks, I get random Xorg lockups too. I can move the mouse but can not click anything. (No reaction) The KDE clock also freezes, so it is the complete screen and not just the mouse not responding.
I am using a Thinkpad T540p with nVidia Optimus. I installed bbswitch to disable the dedicated GPU on boot.
Intel Core i7 with HD 4600 integrated graphic (Kernel driver i915)
GeForce GT 730M (Kernel driver nvidia)
Linux 4.0.4-gentoo

The Kernel log does not show anything, but Xorg.log gets flooded with EQ overflowing.
I am able to kill Xorg with Alt+Print+K and a new instance opens.
These Freezes are hard to reproduce. I can work several days with not even one freeze but then it suddenly freezes a couple of times in a row.
I can not specify a program that could cause the freeze. Most of the time I have open KiCad, Firefox, Okular and Eclipse since I do mostly embedded hardware and sometimes software development with the machine so these are the tools I use.

Xorg.0.log: http://pastebin.com/Eiag0X4Y

Has anyone an idea on how to diagnose this?

By the way, is this thread a collection for all problems with Xorg locking up or should I open an own thread?

Edit: Updated to Linux 4.0.5-gentoo. Let's see if it helps.

Edit 2: Updating to Linux 4.0.5 did not change this behaviour. I have disabled the KDE Desktop Effects on monday and have not had a single freeze since then...

Solution :
Upgrade to kernel 5.5.8 or later.

The CPUgovernor is responsable for this.

I read in in a recent post, not from 5 years ago, who would not mention the 5.5.8 kernel. It is a recent bug.
See (i refound it):
https://stevescargall.com/2020/02/12/how-to-set-linux-cpu-scaling-governor-to-max-performance/
IAlso I found :
https://bugs.launchpad.net/ubuntu/+source/gamemode/+bug/1875740
https://bugs.launchpad.net/ubuntu/+source/gamemode/+bug/1862455 from feb 2020 from Ubuntu.

I think from all those post about freezing a problem in the cpu governor would explain it. And maybe the other distro solved the problem quietly.
It would be interesting if we put it on performance the same problem would occur. Since I noticed that when the cpu is idle the freeze happens.
Not when itis busy.

I had before I upgrade the kernel (4.19.xx) no problem but since I have 5.4.38 and 5.4.48 I have nothing than problems with freezing on ALL my computers. So do everyone a pleasure and mark them as unstable so we won't upgrade to those kernels. And try to get a 5.5.8 one in gentoo-sources. If the freezes are gone then we know it for sure.

With the latest sync the freezes are gone.
but an internal crash remains.
