Jeff, I think this should be merged into 2.6.29 unless Linus still
objects. Linus, as discussed in this thread, this is workaround for a
hardware / firmware problem and vanilla windows also suffers the
problem, so as ugly as it is, we need this to prevent double spin down
on the machine.
Oh, I forgot to reply to this... libata-2.6.git#hibern_regress no
longer applies cleanly.
I'll try poking at it on Monday and get it cleaned up, as it is IMO a
bug fix and still should go in.
