This is a different issue.  libata EH plugs the port if reset fails
repeatedly.  This behavior was implemented to avoid causing continuous
resets on a port in case it has flaky PHY state reporting; however, it
seems to cause more trouble than fixing issues - ie. plugging in a
broken device may end up plugging the port even after the offending
device is removed until manual rescan or reboot.  I've been pondering
about changing the behavior like the following.

Thanks for the explanation, Tejun, and for sending those changes upstream.
I shall incorporate these patches into my kernel and keep you informed as
to how they behave.

Mark, did you get a chance to clean up the sata_mv spinlock addition in
mv_set_main_irq_mask?

Many Thanks,

Bruce.
