While trying to copy tar files to a IOMEGA Jaz drive the following
messages occurred:

Mar 26 22:00:44 apollo /kernel: ahc0:A:1: unknown scsi bus phase.

Now I get the following error messages:

apollo:/var/log$ ls /jaz
ls: /jaz: Input/output error


apollo:/var/log$ umount /jaz
umount: /dev/sd1c: Operation not permitted


I am running Free BSD 2.1.6 with an Adaptec controller. The same setup
worked fine 2 weeks ago. Any ideas ?
