[sane-devel] Trouble with Artec AM12S

[Jody Hay]

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?
