And other kernel panic dump. Daily crashes while making backups are
pretty standard now.
This problem started when the machine was an Athlon 1.4GHz. Since
then, I have replaced literally every component but the tape drive
itself, including an identical model Tekram DC-390F SCSI card (I
bought two a while back and swapped cards between servers for testing).
Is there any additional information I could provide to help out?
