Hi,

while my work on vaapi support for xine lib i face the following problem :

[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
[drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -11 (awaiting 1833878 at 1833876, next 1833879)
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
[drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -11 (awaiting 1833879 at 1833876, next 1833880)

Software :
Archlinux x86:64, kernel 2.6.38. intel git driver, libdrm git, libva git.

Xinelib is using the included VAAPI support in ffmpeg for decoding. The output is done by my own VAAPI output plugin for xine.

The hang only apears on decode MPEG2 Videos, h264 seems so far to be fine.
