[sane-devel] Astra 1220s freezes system

[B Thomas]

Hi,
I am using Astra 1220 (scsi) with Debian/GNU Linux 4.0 (etch),
kernel 2.6.22.1, and sane 1.0.18. After a couple of scans using
xsane the scanner stops scanning often in the middle of a scan.
xsane stops responding and eventually goes into uninteruptable
sleep (state D). Often but not always the entire xserver freezes
and I have to do a hard boot. The kernel spits out i/o error
messages. Any subsequent scsi command also goes to sleep 
immediately. Even if the system is not hung, the xsane process
can not be killed and starting a new one hangs it too.

My scsi card is Domex 3191D. It uses passive termination and the
scanner has two scsi ports, one of which is terminated,(the other
has the cable).

Would be grateful for you tips on how to go about fixing this.
Or is this a bug ? I would gladly provide any further information
required.
