from Marek Ol=C5=A1=C3=A1k
Can you please do this:
- Disable GPU reset by adding this kernel parameter: radeon.lockup_timeout=
=3D0
- Reproduce the GPU hang.
- CTRL+F1. This should switch to text mode successfully if you've disabled =
GPU
reset. You can't got back to X now.
- Save the contents of dmesg.
- Reboot
Attach dmesg here.
If dmesg doesn't contain a VM fault, you don't have to do anything else for
now.
If dmesg contains a VM fault, set this environment variable and start the g=
ame:
R600_DEBUG=3Dcheck_vm
(If it's a steam game, you must get the correct steam run command, which ca=
n be
obtained from the desktop shortcut. For me, it looks like this: steam
steam://rungameid/440 ; Make sure Steam isn't running, then run
"R600_DEBUG=3Dcheck_vm steam steam://rungameid/$number" where $nu=
mber is the game
number)
After you reproduce the hang again, reboot and attach the new files located=
in
~/ddebug_dumps/. Those should be records of VM faults created by
R600_DEBUG=3Dcheck_vm.
I can't promise I will be able to fix this. The issue is kinda random and it
may be fixed by a later kernel or Mesa release.
