[Intel-gfx] [libva] GPU hung

[Angela]

>For gpu hangs the important thing is the i915_error_state file from sysfs
(the files you've attached are mainly interesting for modeset issues). I
guess the best thing would be to file a bug on bugs.freedesktop.org with
that.

Hello Daniel

I get the following:

# cat /sys/kernel/debug/dri/0/i915_error_state
no error state collected
# cat /sys/kernel/debug/dri/64/i915_error_state
no error state collected

mount:
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)

What is wrong ?
