I am getting some strange behavior from my IBM ServeRAID card.  Every once in a while the box locks up and filesystems on the raid channels become essentially inaccessible.  It seems to happen most frequently when I am using the DAT drive (also SCSI, but on a different, on-board SCSI channel), or starting up VMWare while other disk I/O intensive things are happening.

Has anyone seen this kind of problem before?  Is this more likely a hardware or (ips) driver problem?  Or something else, like a SCSI termination problem?

TIA,
Mike
