    I think around a year ago I had problems with weird screen artifacts (some screen lines jittering up and down) on my r9 290 on 4k. Reported that bug to on the amd site and like a month later it was fixed. Pretty cool that they still fix driver issues for the older cards!

      ...... and many more

      Until now I didn't find useful comments resp. this error. Maybe you have a hint how to proceed.

      Sorry to answer late. Unfortunately, I am not too knowledgeable about this. I would ask in #amdgpu on freenode (with a link to the complete log, and mention VM_CONTEXT1_PROTECTION_FAULT), and wait for someone to answer me, to be frank.

      You might also have a bit of luck with enabling GPU recovery:

      (/sys/kernel/debug/dri/0/amdgpu_gpu_recover), see https://www.phoronix.com/forums/foru...54#post1036954

      Though I'm not sure whether your freeze is a complete system freeze, or just GPU? (sounds like the latter). Can you still ssh in? You can also boot with amdgpu.gpu_recovery=1 to enable it automatically.

      Though I wasn't personally very lucky with this (but haven't had crashes/hangs in a long time).
