Just got sata_mv working under the new EH, on my 6041.
It probes and talks to disks just fine (chip doesn't support ATAPI),

Testing on my Adaptec 1420SA (604x, not sure which) gave several BUG()s,
and seemed to mount the drive. I immediately unmounted it, as I got
spooked by the bug reports in dmesg, and I fat fingered ro as rw :(

Thanks much for the testing. This looks quite similar to the BUG()s
that someone emailed me in private (so far the only other tester besides
me and you).
I'll give this a think, and see what I come up with.
I'd love to get this controller running, as I could use the space. I'll
test just about anything you want, but my turnaround is likely to be on
the order of 24 hours or so...
Does the stock upstream driver work for you? It should already be
running, just with prehistoric error handling :)
