Amanda 2.4.4p1
Debian Linux

I finally took the plunge yesterday, and upgraded my last system to
kernel 2.6.3.

Unfortunately, this is my amanda backup server, and under this kernel it
no longer communicates with /dev/nst0:

   # sudo mt -f /dev/nst0 offline
   mt: No such device. Cannot open '/dev/nst0'.

Everything else appears to work as expected.  I didn't notice this tape
problem until this morning, I saw the backup was stuck on holdingdisk.

Running following results in `0' tape devices found:

   # sudo /etc/init.d/mt-st modload

Regardless of kernel, I see this:

   # cat /proc/scsi/scsi
   Attached devices:
   Host: scsi0 Channel: 00 Id: 05 Lun: 00
     Vendor: HP       Model: C1537A           Rev: L812
     Type:   Sequential-Access                ANSI SCSI revision: 02
   . . .

Now, after reboot back into 2.4.25, /dev/nst0 is working fine, and I am
flushing last night's backup to tape as I compose this.

I have searched the archives and Google; but, the string `st' is very
common, and I probably have not found the optimal search string ;>

What do you think?
