Adaptec 2410SA starts doing this: aac0: COMMAND 0xc551a7e8TIMEOUTAFTER 147 SECONDS (Modified by Chad Leigh -- Shire.NetLLC)

[Aaron Wohl]

We got command timeout with the aac driver off and on for about a year
with a 5400s and various freebsd versions.  Ive been sending Scott the
info and he has tried various fixes.  I switched one of the machines to
5.2.1 a couiple of weeks ago.  It been ok so far.  Buts sometimes it may
go a month or two then happen a lot so hard to say for sure yet.

When it has happened to us power cycling and rebooting gets it unwedged
-- reset does not.
