 Posted: Wed Dec 11, 2024 10:28 pm Post subject: intermittent crashing with modesetting |
 |
|
Hello,
I've been experiencing system crashes for a couple months now, specifically, as far as I've tested, when I use modesetting:
| Code: | Section "Device"
Identifier "Intel Graphics"
Driver "modesetting"
Option "AccelMethod" "glamor"
Option "DRI" "3"
EndSection |
But the same does not happen when I use Intel's drivers (setting VIDEO_CARDS to "intel i915", and using sna and crocus), or, at least, they haven't crashed on me yet  .
I've found a very specific setup to trigger this: I'll use Vesktop to share my screen, and eventually (sometimes seconds, sometimes minutes), it'll crash the system. Vesktop will also print "Unrepairable overflow!" sometimes before it happens .
Nonetheless, this happens a lot with Firefox and Discord. Sometimes I'll leave things compiling overnight, with a Firefox window open, and I'll come back to an unresponsive system. SSH doesn't seem to work either.
I was using OpenBox every time this happened.
As of now, I'm using the Intel drivers.
My kernel config: http://0x0.st/Xhhu.txt
emerge --info: https://0x0.st/XhhQ.txt |

It can be several things.
The kernel i915 driver.
The xorg modesetting driver.
Mesa, which is the package doing your acceleration.
That's a big problem space.
Some things to try to narrow it down.
Turn off acceleration completely. You will hate that. If the problem goes away, try a differerent vesion of mesa.
You could just do that anyway.
Then a different kernel.
Lastly, different xorg.

I've done almost all that was suggested:
Changed to a stable Mesa version (24.2.6-r2)
Changed to a stable kernel (=gentoo-sources-6.6.62)
Disabled acceleration
The only time that there wasn't a crash was when acceleration was disabled (Again, I assume it wouldn't crash after more than a couple minutes with it being fine).
On a quick sidenote, I was trying to use Hyprland, to see if somehow Wayland would've fixed the issue, and apparently it also crashed overnight. SSH didn't work either, once again.
Now, I'm not sure if it is exactly related, since I can't seem to use the same setup [with Vesktop], for some odd reason. 
I'll keep using Hyprland for some time, and see if there are any (meaningful) crash logs. |

With acceleration disnbled, mesa is doing little or nothing, so mesa is implicated.
Can you disble 2D and 3D acceleration separately?
if so, that's worth trying.
Has a bug been reported at bugs.gentoo.org for the issue?
Its worth looking now but it would be good to narrow it down further before creating a bug.
If there is a live mesa ebuild -9999, it may be worth a try.
That's the commit by commit as it happens version, so it may not build at all and if it does, it may not work.

I sadly don't think I can, or at least, I don't know a way to do that. My apologies.

I haven't seen any kind of issue like this on the bugzilla for xorg-server, intel_clc, xf86-video-intel, or mesa.
And yes, I would like to narrow this down as much as possible. The assumption currently is that it is mesa's doing, but until we have enough evidence that it is actually that, I'd like to keep looking.

There were no issues with compilation or running the actual thing, but it was no different than the previous tries, sadly. |
