--- Comment #30 from Simon <sur3 at gmx.de> ---
I commented out "//drm_atomic_helper_wait_for_flip_done(dev, state);" now in
intel_atomic_commit_tail(..) in drm/i915/intel_display.c, that seems to fix
some problems probably, at least I did a 2,5h test playing Xonotic and didn't
get any GPU crashes on Xonotic with that patch yet.

I still "get i915 0000:00:02.0: Resetting chip after gpu hang" though with
introduction level of OpenTomb ( https://github.com/opentomb/OpenTomb/ ) with
an additional console message: "i965: Failed to submit batchbuffer:
Input/output error"
That's probably some bug in OpenTomb, but anyway a program bug shouldn't hang
the GPU right? Also on an Ivy Bridge that hang doesn't happen.
