Created attachment 143492 The gpu crash dump

From time to time, (once every couple hours approximately), the graphics system hangs for a few seconds, then returns to normal.

The output from dmesg at the time is: [feb27 19:52] [drm] GPU HANG: ecode 7:0:0x85dffffc, in kwin_x11 [3775], reason: hang on rcs0, action: reset [ +0,000002] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. [ +0,000000] [drm] Please file a new bug report on bugs.freedesktop.org against DRI -> DRM/Intel [ +0,000000] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. [ +0,000001] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it. [ +0,000001] [drm] GPU crash dump saved to /sys/class/drm/card0/error [ +0,000043] i915 0000:00:02.0: Resetting chip for hang on rcs0

Thanks a lot.
