GPU crash dump
I get GPU hangs on Sky Lake integrated graphics when not booting with either:
i915.modeset=0
or
video=vesafb:off
The hardware is a Dell 7040 with Intel i7-6700 CPU.
Xorg does not crash, but everything except the cursor locks up each time the
GPU resets. Here his the drm message:
[ 41.823218] [drm] GPU HANG: ecode 9:0:0x859ffffb, in Xorg [2092], reason:
hang on rcs0, action: reset
[ 41.823219] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 41.823220] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 41.823220] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 41.823220] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ 41.823221] [drm] GPU crash dump saved to /sys/class/drm/card0/error
Subsequent to this there are frequent repeated resets:
[ 92.731613] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0
[ 100.731570] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0
[ 108.731500] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0
[ 116.731410] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0
[ 606.840675] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0
[ 617.816522] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0
[ 625.816467] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0
[ 633.816354] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0
Kernel: 4.17.0
Xorg server: 1.19.6
Intel driver: 2.99.917+git20171229-1
Mesa: 18.0.0
GuC firmware: i915/skl_guc_ver9_33.bin
HuC firmware: i915/skl_huc_ver01_07_1398.bin
I started out with a stock Ubuntu Xenial and progressively upgraded bits with
no avail. Turning off modeset/vesafb was an acceptable solution until I needed
dual display support.
