Created attachment 140539 [details] 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.
