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).

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.That a problem, latest working baseline I tested and confirmed passing hotplug tests is this branch and commit https://gitlab.freedesktop.org/agd5f/linux/-/commit/86e12a53b73135806e101142e72f3f1c0e6fa8e6 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).

I copied the complete dmesgs as follows. I highlighted the OOPSES for you.
