We had kernel problem.

I wanted to read the backup on SDLT from a remote machine, but it failed. I gave the command mt -f / dev/st1 on the
local machine. I did not receive any answer. The status of the 'mt' process was: Duninterruptible sleep (usually IO).
The system produced a lot of messages to/var/log/messages,
and stopped with Kernel Panic message: beta kernel: Kernel panic: Waiting List traversal
