--- Comment #37 from Tom B <tom at r.je> ---
5.1.9 makes this bug even worse. It now crashes as soon as the display server
is started.

Running sensors now gives an error:

I can't even see the wattage now.

No clocks or wattage! 

I'm guessing 34d07ce3d6a120056e4763ae9a3db0d769ab7c63 "fix ring test failure
issue during s3 in vce 3.0 (V2)" is to blame as dmesg (attached in next post)
says


[   20.584937] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout,
signaled seq=25, emitted seq=27

It would be nice to see some acknowledgement from AMD on this.
