Xorg log

On starting X windows or very soon after the keyboard and mouse response
was slow and got this in /var/log/messages :-

Dec  7 05:52:23 localhost kernel: [drm] GPU HANG: ecode 5:0:0xeeccffff, in Xorg [784], reason: hang on rcs0, action: reset
Dec  7 05:52:23 localhost kernel: [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
Dec  7 05:52:23 localhost kernel: [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
Dec  7 05:52:23 localhost kernel: [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
Dec  7 05:52:23 localhost kernel: [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
Dec  7 05:52:23 localhost kernel: [drm] GPU crash dump saved to /sys/class/drm/card0/error
Dec  7 05:52:23 localhost kernel: i915 0000:00:02.0: Resetting chip for hang on rcs0

The system was just about usable but very slow. I shut X down and started it
up again and it was still slow. It was all ok again after a full reboot.

I had installed kernel-4.19.7 the previous day and had booted and run with
kernel-4.19.7 four times during the day without any problems.

------------------------------------
Hardware:
  Asus P7H55-M SI with Intel Core i5 processor
  and Integrated Graphics [i915 driver].

Distro: Slackware-14.2, but with newer kernel.
------------------------------------

Will attach Xorg.0.0.log file and error file.

Something overwrote a portion (one tile) of the batchbuffer. We only caught the damage, not the culprit.

William, Do you still have this issue?
Have you tried to verify with drmtip (https://cgit.freedesktop.org/drm-tip)?
