possible bug in 6.2.36

We have a raid array consisting of 4 external promise raid  devices
attatched to an Adaptec 29160 SCSI adapter in a redhat 7.3 box running
kernel 2.4.24. One afternoon the kernel paniced, we thought because
of a problem with JFS. We rebooted and noticed in syslog that
there are many SCSI errors, including the one immmediatly 
below which asks us to file a bug report.


Is this a problem with the driver, the card itself, or the promise raid 
devices?
