<pre>Hi Rodrigo:
I turn on the debug, and the kernel message is as followed:

<6>[ 494.596034] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.

PS. I cannot find /sys/kernel/debug/dri/0/i915_guc_load_status node.
Is there any debug option I need to setup?
Thank you!
Cheers,
