Hi David,
You could try and load/unload the st module by hand and then
check /var/log/messages for any errors:

:: remove the st module
# modprobe -r st

:: notice there is no /dev/nst0 device
# ls -l /dev/ns*
ls: /dev/ns*: No such file or directory

:: load the st module
# modprobe -a st

:: st has created the /dev nodes
# ls -l /dev/ns*
crw-rw---- 1 root disk 9, 192 Nov  5 20:38 /dev/nst0m
crw-rw---- 1 root disk 9, 160 Nov  5 20:38 /dev/nst0l
crw-rw---- 1 root disk 9, 128 Nov  5 20:38 /dev/nst0
crw-rw---- 1 root disk 9, 224 Nov  5 20:38 /dev/nst0a

:: dmesg shows tape drive status
# dmesg | tail
st: Unloaded.
st: Version 20050830, fixed bufsize 32768, s/g segs 256
st 8:0:5:0: Attached scsi tape st0
st0: try direct i/o: yes (alignment 512 B)


Not sure what's causing the issue, but that should give you something to go on.
Cheers,
Thomas
