AMDGPU fence info

I've tested text mode and gui/drm mode with "drm.debug=0x1ff" set and found no
crashes... when "drm.debug=0x1ff" is unset... the crashes/timeouts are back...
I think this is why your unable to reproduce the problem...

I've never known debug option(s) to remove issue(s)... oh well

I've added the contents of the file
"/sys/kernel/debug/dri/0/amdgpu_fence_info".

The file contains 4 different boot states ( vcn on/off, drm debug on/off )
clearly marked/seperated in the attached file

I'm using 5.12.5 now but I also tried this on 5.12.4. Usually the crashes
happen within 50 suspensions/resumes but today I left it to do over 2000
suspensions/resumes just to make sure...

I know you asked for a log but I spent so much time on this ( other things too
), it wasn't on my mind so I'll get that by Friday, if you still need it
ofcourse

thanks
