Subject2.0.33 oops while using ide tape

After about 1 day and 3 hours uptime, I got an oops during the system backup:

The system looks stable, but the streamer will only be available after a
reboot... :(

Windows NT 4.0 does no longer support i386 processors ?
Get a Pentium Pro, no one will notice the difference !
