crash dump.

I'm getting random GPU hangs as well as display corruption (random parts of the screen will show tearing/lines with various colors) quite often. It's very hard to accurately reproduce, but happens pretty consistently when scrolling in Firefox or typing in vim in a terminal.

Running Fedora 28 x86_64 on 4.17.3-200.fc28.x86_64. I'm using a skylake Lenovo p50 with hdmi hooked up to an external 1080p monitor.

Here's the dmesg dump. I get a crash log for the first one. Later ones just show the "Resetting rcs0" message.

[ 4732.361391] [drm] GPU HANG: ecode 9:0:0x85dffffb, in gnome-shell [2235], reason: Hang on rcs0, action: reset
[ 4732.361392] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[ 4732.361393] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[ 4732.361393] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[ 4732.361393] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
