Looks like all of these errors are from a FLUSH CACHE command and the

That's not a DMA-mapped command, so it wouldn't go through the ADMA
machinery and I wouldn't have expected this to be handled any
differently from before. Curious..
It's possible the flush-cache command takes longer than 30 seconds, if
the cache is large, contents are discontiguous, etc. It's a
pathological case, but possible.
Or maybe flush-cache doesn't get a 30 second timeout, and it should...?
(thinking out loud)

If the flush was still in progress I would expect Busy to still be set,
however..
