Hello.
|
|
<BR>
|
|
<P>I'm using an Agfa 1236S with the snapscan backend (src-1.0.tar.gz).
|
|
<BR>
|
|
Scanimage (for example) doesn't work and left the computer in a funny
|
|
<BR>
|
|
state. Actually, the driver hangs, and since I've only SCSI disks,
|
|
<BR>
|
|
everything slowly blocks as disks are solicited. The kernel log shows
|
|
<BR>
|
|
that requests to disks (on the same scsi card) timeout.
|
|
<BR>
|
|
<P>The problem can be traced back to the piece of code requesting scanner
|
|
<BR>
|
|
self-test. I just commented out that portion (diff -u included at the
|
|
<BR>
|
|
end of this message) and everything works fine. I believe the problem
|
|
<BR>
|
|
to be actually in the generic SCSI driver (that shouldn't crash so
|
|
<BR>
|
|
badly whatever trash may be sent to it), however this is a workaround.
|
|
<BR>
|
|
<P>Regards,
|
|
<BR>
