Hi,
<BR>
<P>&nbsp;&nbsp;&nbsp;I've resolved that SCSI IRQ problem but still: In the old machine (a
<BR>
PIII running 2.4.1-pre something kernel), I can use my scanner and
<BR>
everything works, but when I move the AHA2940 adapter and scanner to
<BR>
the new machine (an Athlon running 2.4.5), the resulting images are
<BR>
only garbage. Everything else seems normal, i.e. I don't get any error
<BR>
messages or SCSI timeouts or such, it's just that the data returned is
<BR>
bad.
<BR>
<P>On both machines, the scanner is the only device on the SCSI bus.
<BR>
<P>I have tried it with a sane version compiled on the new machine, and I
<BR>
have also tried using the binaries from the old machine; both have the
<BR>
same problem.
<BR>
<P>I am attaching a debug printout from a small color test scan. The
<BR>
&quot;fujitsu&quot; debug lines all seem ok. Can anyone tell me if the
<BR>
&quot;sanei_scsi&quot; debug lines look all right, or if you can spot some
<BR>
potential problem there.
<BR>
<P>Any other ideas?
<BR>
<P>Thanks
<BR>
Frederik
