I have been having an infrequent problem scanning
with my Artec AM12S. Usually within the first ten
scans after a reboot, something seems to lock up
the computer.
Here are some details:
Debian "testing" distribution
custom 2.4.16 kernel, patched with XFS
SCSI module dmx3191d (card bundled with Scanner)
libsane 1.0.6-0.1
Here is an example of what happens when the computer locks up:

After the machine had been locked for 10 minutes, I powered
off the scanner. The computer came back (I could type commands)
but the scanner was no longer shown. Any ideas?
