The system appears to have locked up just before 6am EDT. I power cycled
it remotely around 7:30am EDT. Frank was on the box just after it came
up and I assumed he would take a look at things.

Fwiw, I watched the raid array start up via remote serial console:

Note the lack of error messages concerning a failed disk or running in 
degraded mode.

I do know that there are open issues with the aacraid driver that manifest
as random hard locks, sometime occuring infrequently, other times the driver
doesn't last a week. It depends on the version of the aacraid hardware and
also the version of the aacraid firmware.

For more info: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=92129

Filtering out the crap, it looks like Adaptec has the problem fixed in the
latest version of the driver.
