I think filing a PR is a good move. Then just be proactive and poke
people about it. It'd be good to get this fixed. :)
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?
Not a recent CURRENT but on 8.2-RELEASE we have seen recovery on
secondary ssd drives without a panic, but it does generally
drop the disk and need a power off, power on to recover the
disk properly; although we believe that's a firmware bug on
the ssds
