It's possible we have been suffering from two separate bugs that both
cause device timeouts, and in both cases the timeouts were triggering
the same third bug causing panics during recovery.
Since my PR 56479 was specifically about the panics, I have now filed
a separate PR 56686 about the timeouts. If your timeout problem was
indeed specific to AMD chipsets, mine must be unrelated because my
machine has an Intel chipset.
