kernel crash log

I have had this problem for a long long time on amd discrete gpus (currently Vega). Suspend and hibernate fail every few cycles. I have looked at [204241/(https://bugzilla.kernel.org/show_bug.cgi?id=204241) but none of the patches have helped; indeed the patches appear to have already applied post 5.4.3.

Using the internal video (intel i915) stops all suspend and resume failures, so it's very likely to be the amdgpu drivers.

I can test kernel versions up to 5.7 since my root filesystem is on zfs, and openzfs does not compile on 5.8.

Attached logs follow.
