<EM>&gt;&gt; I have gotten rid of the crash by going back to sane-1.0.1 :-(
</EM><BR>
<EM>&gt;&gt;
</EM><BR>
<EM>&gt;&gt; So the problem doesn't seem to be in the scsi drivers.
</EM><BR>
<EM>&gt;&gt;
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; There seems to be a complex combination of reasons... Yesterday evening,
</EM><BR>
<EM>&gt; I played a little bit with the aha1542 driver, and it seems that the
</EM><BR>
<EM>&gt; driver detects a corrupted scatter-gather list (== fragmented buffer)
</EM><BR>
<EM>&gt; for the SCSI data. The aha1542 works fine, if the maximum required
</EM><BR>
<EM>&gt; buffer size is 32 kB. As soon as the buffer size is increased to 32769
</EM><BR>
<EM>&gt; bytes, I get the kernel crash,
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; Therefore, you might try to configure sane-1.0.2 with the option
</EM><BR>
<EM>&gt; --enable-scsibuffersize=32768
</EM><BR>
<P>That gets rid of the crash. Thank you very much! I've only got another problem
<BR>
with using xsane as a Gimp-plugin: Gimp displays a checkerboard instead of the
<BR>
scanned image data. :-(
