  Hello.

  I'm using an Agfa 1236S with the snapscan backend (src-1.0.tar.gz).
  Scanimage (for example) doesn't work and left the computer in a funny
  state. Actually, the driver hangs, and since I've only SCSI disks,
  everything slowly blocks as disks are solicited. The kernel log shows
  that requests to disks (on the same scsi card) timeout.

  The problem can be traced back to the piece of code requesting scanner
  self-test. I just commented out that portion (diff -u included at the
  end of this message) and everything works fine. I believe the problem
  to be actually in the generic SCSI driver (that shouldn't crash so
  badly whatever trash may be sent to it), however this is a workaround.

  Regards,
