Bug description:
I am quite often getting GPU hangups and machine freezes, and the
following is in my logs:
Nov 19 21:17:09 derp kernel: [131426.756136] Watchdog[8655]: segfault at 0 ip
00007fcbb70bc72e sp 00007fcba7692650 error 6 in chrome[7fcbb3514000+5eff000]
Nov 19 21:17:17 derp kernel: [131434.757554] [drm:i915_hangcheck_elapsed]
*ERROR* stuck on render ring
Nov 19 21:17:17 derp kernel: [131434.757557] [drm] capturing error event;
look for more information in /sys/kernel/debug/dri/0/i915_error_state
Nov 19 21:17:17 derp kernel: [131434.785406] [drm:i915_set_reset_status]
*ERROR* render ring hung inside bo (0xef56000 ctx 13) at 0xef561c8
A quick grep for "IPEHR" in i915_error_state gives the following:
IPEHR: 0x79050005
IPEHR: 0x00000000
IPEHR: 0x0b140001
Freedesktop.org Bug #70151 says the following:
Fixed in Mesa 9.2.3 (out today), the upcoming Mesa 10.0 release, or Mesa
master.
This fixes the Sandybridge-specific GPU hang where i915_error_state (aka
/sys/class/drm/card0/error) lists an IPEHR of 0x79050005.
Therefore I think Mesa should be upgraded to at least 9.2.3 to fix
this.
