[1.] One line summary of the problem:
Kernel panic during BUSLOGIC SCSI tape write
[2.] Full description of the problem/report:
When amflush runs on my new Amanda backup server, the kernel panics. The
crash is 100% repeatable, and it always panics at the exact same spot.
The specific command I invoke is:
'su backup -c /usr/sbin/amflush daily'
(as root)
[3.] Keywords (i.e., modules, networking, kernel):
kernel scsi scheduler idle
[4.] Kernel version (from /proc/version):
Linux version 2.4.18 (root@heliodor) (gcc version 2.95.4 (Debian prerelease))
