kernel 2.6.5 on AMD64 [your experiences?]

markuslk

Hi
I've just installed kernel 2.6.5 on my gentoo-64 system and it's working nice and stable :-)

But I had compile errors when I enabled the ACPI Support; genkernel wasn't able to build the bzImage. Well, ACPI doesn't seem to work here, so I'm not missing it at all :-)

The second problem was that I build the Ethernet over Firewire Support as a module, and this module wants to be the first network card in the system...

I'm also running with 2.6.5 and it seem fast and stable.
The only issue I have is that my soundcard don't want to work with it (it run perfectly on 2.6.4, wit alsa via drivers).

Had exactly the same problem with the ieee1394 firewire ethernet taking over eth0/, but a quick compile later with that option removed and all back nicely!

aMule doesn't seem to like it though... it used to crash on 2.6.3, but now it completely hangs 2.6.5...

Will investigate later.

Right, gave up... machine kept freezing when running kde... was fine once I did an "init 1" and went back to console mode... where I tried emerging lots and lots and lots of things... xfree, glibc, kde... but when I restarted, back to freezing...

Back running a nice more stable 2.6.3-gentoo-r2 for the moment... unless anyone can tell me what I would need to re-emerge once I upgrade the kernel...

dropped in my .config from my 2.6.3-gentoo-r2, ran make oldconfig, answered a few questions, built it, installed it and it works fine so far.

time will tell....

I've been forced to go back to 2.6.3-r2 :cry:

When I tried using 2.6.5 everything was fine until my ram would fill up and xscreensaver would activate. Then my system would just reboot.

No error messages, no segfaults... nothing, just a reboot!

Thank goodness I didn't delete my old kernel or modules.

...eep. I'm not even going to TRY 2.6.5, I'll stay with 2.6.4 and wait for 2.6.6

I wanted to try it out because I still can't copy any large file at gigabit speeds on my MSI Neo board with it's realtek ethernet. Anytime I try and use samba or ftp to transfer a large file it locks the machine hard, and it's done that for 2.6.1 to 2.6.4. No change in 2.6.5.

The only change was now when I try and play files (xvid/svcd/divx/etc) with xine or mplayer over the network it eventually chokes, pauses for a couple seconds, then continues on seconds ahead of where it stopped. Reverted back to 2.6.3-r2 which doesn't have that problem.

Everything else seemed to work, nothing crashed it minus the typical gigabit problems.

Anybody have a solution for the video files choking? The kernel was the only (heh, only) thing I changed...

Having spent a little bit more time looking into this I think I will bootstrap my machine again when gcc 3.3.4 comes out... that way I will have the benefit of the better kernel, and the benefit of the faster/better gcc...

As for me, going straight to 2.6.5 no problem at all

Try Brad House's kernel patch ebuild. It works wonderful here. it's geared toward the amd64 platform.

Well I dunno what changes they made between gentoo-dev-sources-2.6.5 and gentoo-dev-sources-2.6.5-r1, but whatever they did, thanks!

It works like a charm so far... which is more than I can say about 2.6.5, which crashed/froze after a few minutes, or sometimes even a few seconds!

Will give it a good run in to see how it goes, but still have 2.6.3-r2 ready as a backup :lol:

Take that back... just hung on me... and no error message!
Back to 2.6.3-r2 we go!

The only thing I can find different in the bootup between 2.6.3-r2 and 2.6.5-r1 relates to powernow...

For 2.6.3-r2

I just got my AMD64 3200+ this week.

I have tried both mm-sources and gentoo-dev-sources without any problems other than that the mm-sources was not as responsive as gentoo-dev-sources is.

Both are 2.6.5...

I guess it is a bit early yet to say any definite, but so far, no problems.

2.6.5 with a combination of recompiling my system with out the mfpmath flag got rid of my system rebooting when I tried to acces glx.
So no problems so far.

I've had my dual opteron CPU hardlock, usually when doing CPU heavy stuff and either clicking on a link or changing a song in XMMS...

I do not remember this error with the 2.6.4 kernel for the time I used it (only ~week)...

May I perhaps suggest IRQ issues? I guess it's a place to start, just got done talking with someone in the gentoo-amd64 IRC channel and he had these kind of issues with 2.6.3, but is stable with 2.6.5. I'm wondering if it may not depend on the kernel at all?

Definitely some funky stuff going on here.

Well, I've been using the 2.6.5-r1 kernel for 24 hours, and so far I've had no problems. The reboot problem that I experianced with 2.6.5 is nowhere to be found

and everything else seems a little more responsive than with 2.6.3-r2

I'm still going to keep my old kernel and modules around for a while, but so far, it looks like 2.6.5-r1 is a winner on my dual Opteron system.

What I want to know is why, with all these problems, 2.6.5 is marked stable and 2.6.4 is not.

Have a Shuttle SN85G (nforce3 150), Leadtek gForce 5700 ultra, 1 gb DDR400, 120GB ata133 HD, and an AMD64 3200. Been running the 2.6.5 kernel for about a week. I did a stage3 install and everything work fine from the get go. Like many other posting, my firewire came up as eth0 which caused me some greif till I figured out what was going on. My system running gnome has been solid running many diffrent apps (ut2004demo, xine, mplayer, samba, xmms, firefox, etc). There are a few detail I am still sorting out, but I think are due my errors. Over all I am really enjoying my gentoo amd64 experience.

If you're getting hard locks, reboots or similar, remove any traces of "-mfpmath=" from your CFLAGS and do an emerge -e world. Not only does it break certain things on AMD64, but each of -mfpmath=387, -mfpmath=sse and -mfpmath=387,sse give slower performance on almost all - AMD64 included - architectures.
