--- Comment #6 from Charles Samuels <charles at kde.org> ---
But I can't fix the problem even with "i915.semaphores=1 i915.i915_enable_rc6=0
i915.i915_enable_fbc=0 i915.i915_enable_ppgtt=0"
and then `echo 0 > powersave` does not help
In my case, I can boot up and turning on composition (kwin) triggers it
immediately. Without composition, firefox triggers it pretty easily.
Eventually I get this:
[ 905.161034] [drm:i915_reset] *ERROR* GPU hanging too fast, declaring wedged!
[ 905.161039] [drm:i915_reset] *ERROR* Failed to reset chip.
And then glxgears segfaults on startup.
