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.
