(If this belongs on another list, please let me know.)

I have a system that I've been using for amanda backups of my network for a
couple of years.  It's currently running 2.2.8-STABLE and amanda-2.4.1p1.
As of a few months ago, I have been unable to get 1 local and 1 remote
filesystem to back up to tape on this machine.  If I do a simple "dump" of
the problem local filesystem to tape, it works.

I have tried backing up these two filesystems using almost all combinations 
of (no) holding disk / (no) compression.

I've cleaned the heads and tried a number of fresh new tapes.

Anyway, I get the following message upon failure:

Dec 19 22:10:57 pcfb1 /kernel: st1(ahc0:5:0): Target Busy
Dec 19 22:10:57 pcfb1 last message repeated 5 times

dmesg for the SCSI stuff is:

ahc0 <Adaptec 2940 SCSI host adapter> rev 0 int a irq 11 on pci0:10:0

The tape drive is last on the chain and is internally terminated (active, 
as I recall).

Any ideas?  I'd really like to get all of my backups working cleanly again.
