Anyway, what's annoying is that I can't figure out how to bring the

enclosure,
but power cycling the drive doesn't seem to help. I thought libata
hotplug
was working? (SiI3132 card, using the sil24 driver.)
Yeah, it's working but failing resets are considered highly dangerous
(in that the controller status is unknown and may cause something
dangerous like screaming interrupts) and port is muted after that. The
plan is to handle this with polling hotplug such that libata tries to
revive the port if PHY status change is detected by polling. Patches
are available but they need other things to resolved to get integrated.
I think it'll happen before the summer.
Anyways, you can tell libata to retry the port by manually telling it to
rescan the port (echo - - - > /sys/class/scsi_host/hostX/scan).
I won't say that's voodoo, but if I ever did it I'd wipe down my
keyboard with holy water afterward. ;-)
Well, I did save the message in my tricks file, but it sounds like a
last ditch effort after something get very wrong.
