Per advice from Doug Ledford I'm posting this here, as he doesn't feel
its a SCSI issue.
Recently on the LInux box I'm running I'm seeing oops usually during
tape backup using the BRU package that comes with Caldera Open Linux
2.3 running kernel 2.2.13.
System Specifics:
Linux 2.2.13
256MB RAM
Celeron 333 Processor
Adaptec 2910B Controller
Disk Drives:
hda: SAMSUNG SV0844A, ATA DISK drive
hdb: FX240S, ATAPI CDROM drive
hdc: WDC AC32500H, ATA DISK drive
SCSI DISK ID #1 sda: SEAGATE Model: ST32550N Rev: 0021
Tape Auto Changer ID#3 HP Model: C1553A Rev:NS01
Included below are syslog, dmesg output and the results from running
through ksymoops.
Any suggestions or thoughts appreciated, this used to be a rock solid
system.
