[sane-devel] Umax Astra 1200S freezing up

   When  I was using Umax 1220S with the  LSI Logic / Symbios Logic 
(formerly NCR) 53c875 (rev 03)
SCSI card, I experienced the same problem in average about every 50 scans.

If I remember well... (let me know):
   I assume, that this has something to do with the SCSI error feedback 
capability in Linux drivers.
That is perhaps also the reason for SCSI being rewritten (Hopefuly 
before 2.6), unfortunately not
exactly the way Jorge Shilling of cdrecord wanted, that is SCSI errors 
being able to callback the
calling application.
