I encountered the same issue, and was able to bisect. I'm pasting the

drm/amdgpu: Add more checks to PSP mailbox
[ Upstream commit 8345a71fc54b28e4d13a759c45ce2664d8540d28 ]
Instead of checking the response flag, use status mask also to check
against any unexpected failures like a device drop. Also, log error if
waiting on a psp response fails/times out.
