Done, kern/161768.

Question to the list: does anybody see successful recovery from AHCI
timeout an a recent CURRENT? Recent means June 2011 or newer, so 9.0
branch counts also. That is, there are some kernel messages like this:

ahcich0: Timeout on slot 29 port 0
ahcich0: is 00000000 cs 00000000 ss ffffffff rs ffffffff tfd 40 serr 00000000 cmd 0000fc17

but then AHCI recovers and the system does not panic?

Poking Alexey.
