GPU hang error state
Tested the driver with the commit that caused the scrn assert error reverted.
Pitch/tiling bugs indeed remain, and I haven't managed to trigger the original
bug, but I got a (long) GPU hang. :(
[ 468.733033] arch_pc kernel: [drm] GPU HANG: ecode 4:0:0xf2a7fff8, in Xorg
[430], reason: Hang on rcs0, action: reset
[ 468.733037] arch_pc kernel: [drm] GPU hangs can indicate a bug anywhere in
the entire gfx stack, including userspace.
[ 468.733039] arch_pc kernel: [drm] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
[ 468.733040] arch_pc kernel: [drm] drm/i915 developers can then reassign to
the right component if it's not a kernel issue.
[ 468.733041] arch_pc kernel: [drm] The gpu crash dump is required to analyze
gpu hangs, so please always attach it.
[ 468.733043] arch_pc kernel: [drm] GPU crash dump saved to
