>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).

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 ?
