I mailed the list a while ago about the ncr53c8xx SCSI driver hanging the
system with SCSI timeouts a while ago on a Motorola PowerStack with the
2.4.x kernels.  I am running xntpd at boot time.  I can (will) try
disabling it and seeing if a 2.4.x kernel stays up for a longer period of
time (typically less than 6 hours previously).
