Created attachment 142307 [details] GPU Crash Dump Using Kubuntu 18.10 on Kernel version: 4.18.0-10-generic While using the system, random freezes are occuring, lasting from 5 to 20 seconds, mouse keeps working but everything else is unresponsive. KWin crashes and restarts, and the notification pops: "KWin: Desktop effects were restarted due to a graphics reset". I'm having around 5-6 crashes on a 10 minute period. Running dmesg I get: [ 920.806022] [drm] GPU HANG: ecode 6:0:0x87e8effd, in chrome [4579], reason: hang on rcs0, action: reset [ 920.806024] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.

One of those fun little snb bugs where the CS keeps on going but the GPU stops responding.
I have a 'gpu hang' issue as well. May be a different or the same root cause. My investigation to my situation shows that this is directly or indirectly a kernel issue. See here: https://bugs.freedesktop.org/show_bug.cgi?id=107420.
