i915 error state

Hello,

got a Core i5-3470S which has an HD2500 and an ASUS P8H67-M Evo Motherboard and have problems getting the X Server running smoothly.

Installed everything as it is described in https://wiki.archlinux.de/title/X and for the Intel driver https://wiki.archlinux.org/index.php/intel

I have very ugly distortions and then after some interaction the X Server crashes and restarts.

Here are some infos about my system:

# cat /etc/X11/xorg.conf.d/20-intel.conf

"sna" seems to make more problems than "uxa".

Hope you can help me to get it running.

Don't enable FBC, do the problems go away?

Removed from GRUB and it has no real effect. 

For now I have the problem when I start the computer and first start the X server he has the graphic distortion. When I then click around after some time the X server hangs, restarts and looks ok.

Hello,

after I updated my xf86-video-intel driver to 2.20.1-3 I recognized this error in the X Server log:

[  1100.319] (EE) intel(0): Detected a hung GPU, disabling acceleration.

When I start the X server I get terrible distortion. After I started a console a tried glxdemo, the server hangs and restarts. After that everythings get better. I will add an attachment of i915_error_state and dmesg.

Hope this will help you.

I pushed a potential fix to http://cgit.freedesktop.org/~ickle/xf86-video-intel/log/?h=ivb-gt1 if you are able to test, that would be fantastic.

Ok, will try it tomorrow.

The ddx portion will be fixed by

commit 1ced4f1ddcf30b518e1760c7aa4a5ed4f934b9f5

    Reduce maximum thread count for IVB GT1 to avoid spontaneous combustion
    
    Somewhere along the way it seems that IVB GT1 was reduced to only allow
    a maximum of 48 threads, as revealed in the lastest bspecs.

however a similar patch is required for mesa.
