FYI, this is what we have seen on our aacraid systems under heavy I/O
and CPU load.  It's unclear at this time if this is a firmware issue
or a driver issue, but I do know that now Dell and Adaptec are working
on a resolution...

Turning off write caching will provide a work around, although you
will still get timeouts, it looks as though the crashes will be prevented.
