This happens frequently with Promise TX2/TX4 (less frequently in
RELENG-7 than RELENG-6) and issue is probably related to controller
driver.

Unfortunately, nothing showed up in /var/crash, which I think is odd.
I'll update my -STABLE, rebuild my kernel with debugging, and hope to
catch something next time.
In this case controller probably loose whole drive (disconnected and
dissapear from 'atacontrol list'), that's why you see no core dropped,
and powering machine off and on let it recognize the drive again. I have
this issue from time to time with TX4, but fortunately i have 2 disks in
gmirror, so when one drive disconnect I force rebuilding mirro by just
powering machine off and on.
You're using 7.2-stable, so it seems that OS upgrade won't help you
(after upgrade from FreeBSD 6 to 7 issue has been seen 80% less
frequently for me), so my one and only suggestion for you is using
different PATA controller if you can.
