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 for no good
reason 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.
