Unfortunately, I was not able to catch the backtrace of kwin. The kernel said Aug 03 13:12:00 r-schnelltop kernel: [drm] stuck on render ring Aug 03 13:12:00 r-schnelltop kernel: [drm] stuck on blitter ring Aug 03 13:12:00 r-schnelltop kernel: [drm] GPU HANG: ecode 0:0xf4e9fffe, in Xorg [955], reason: Ring hung, action: reset Aug 03 13:12:00 r-schnelltop kernel: [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. Aug 03 13:12:00 r-schnelltop kernel: [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel Aug 03 13:12:00 r-schnelltop kernel: [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. Aug 03 13:12:00 r-schnelltop kernel: [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it. Aug 03 13:12:00 r-schnelltop kernel: [drm] GPU crash dump saved to /sys/class/drm/card0/error Aug 03 13:12:00 r-schnelltop kernel: [drm:i915_context_is_banned] *ERROR* gpu hanging too fast, banning! Aug 03 13:12:02 r-schnelltop kernel: [drm] Enabling RC6 states: RC6 on, RC6p off, RC6pp off I have to reboot now, something else seems to hang as well (my current suspect is d-bus) and the machine is mostly unusable.
