kernel log

Hello!

I just triggered a kernel crash while trying out some game in wine (the same as in bug #33066).

Jan 15 23:17:22 voodoomaster kernel: BUG: unable to handle kernel paging request at ffffc90010280000

When loading the intro sequence in FEAR the screen suddenly went blank and switched back to console to display this error. The full error is attached as textfile.

Could still log into the machine via ssh and salvage the kernel log.

System:
ATI Technologies Inc Radeon HD 4770 [RV740]

drm-radeon-testing kernel
libdrm, mesa and xf86-video-ati are all git master
xorg-server-1.9.3.901

wine is version 1.3.11 and the game I triggered this with is the FEAR demo:
http://www.gamershell.com/download_10167.shtml

GLSL was enabled in wine.

Greets,
Tobias

Does it works any better now ?
Comment 3 Tobias Jakobi 2011-03-08 12:22:30 UTC 
No, not really. But I'd like to add that the GPU resets (which eventually lead to a complete crash) only appear when using DX9 level shaders. With DX8 level shader (you can select this ingame) it works kinda good.
Comment 4 Tobias Jakobi 2011-03-08 13:14:15 UTC 
HL2 engine based games also seem to be particularly good in triggering a kernel crash, at least when a DX9 render path is selected.

E.g. I have HL2 (vanilla) running here with mat_dxlevel 81 (this is a DX8 renderpath with some additional eyecandy -- see http://developer.valvesoftware.com/wiki/DirectX_Versions for more information) and all gfx settings ramped up. This works kinda good (lots of lighting errors) and more importantly: I doesn't trigger any GPU resets or crashes.

However once I select a 9x dxlevel, the GPU resets start and my system doesn't survive more than 10 seconds.
Comment 5 Tobias Jakobi 2011-05-06 17:27:34 UTC 
Still happens with mesa git master (6bb230970cb2da5e3fe9bc63991b4b5f92445e92) and DX level 9 shaders.
Comment 6 Tobias Jakobi 2011-07-03 06:06:03 UTC 
I'm setting this one to FIXED, since I can no longer reliably reproduce the crashes with either FEAR nor the HL2 engine in DX9 shader mode.
