The only one in Radeon 7 I see is the same sysfs crash we already fixed
so you can use the same fix. The MI 200 issue i haven't seen yet but I
also haven't tested MI200 so never saw it before. Need to test when i
get the time.
So try that fix with Radeon 7 again to see if you pass the tests (the
warnings should all be minor issues).

That a problem, latest working baseline I tested and confirmed

which is amd-staging-drm-next. 5.14 was the branch we ups-reamed the
hotplug code but it had a lot of regressions over time due to new
changes (that why I added the hotplug test to try and catch them
early). It would be best to run this branch on mi-100 so we have a
clean baseline and only after confirming this particular branch from
this commits passes libdrm tests only then start adding the KFD
specific addons. Another option if you can't work with MI-100 and
this branch is to try a different ASIC that does work with this
branch (if possible).

OK I tried both this commit and the HEAD of and-staging-drm-next on
two GPUs( MI100 and Radeon VII) both did not pass hotplugout libdrm
test. I might be able to gain access to MI200, but I suspect it would
work.
I copied the complete dmesgs as follows. I highlighted the OOPSES for you.
