Hi,
|
|
<BR>
|
|
<P>I got several reports of SCSI problems with Mustek scanners in the
|
|
<BR>
|
|
last days. I don't think that these are mustek-bugs. The bug reporters
|
|
<BR>
|
|
provided the following common facts:
|
|
<BR>
|
|
<P>* Linux 2.4.x
|
|
<BR>
|
|
* a SCSI controller that has a queue depth of 1 (e.g. Adaptec 1520)
|
|
<BR>
|
|
* SuSe 7.x (may be coincidence)
|
|
<BR>
|
|
<P>They tried to scan an image but they only get the first stripe of
|
|
<BR>
|
|
aprox. 64k that is repeated until the page is completely scanned. The
|
|
<BR>
|
|
scanner stops after this first stripe. Sometimes the system freezes
|
|
<BR>
|
|
completely, sometimes there is only an error message and sometimes no
|
|
<BR>
|
|
error is output at all.
|
|
<BR>
|
|
<P>I tried to reproduce this bug but couldn't until I did the following:
|
|
<BR>
|
|
rename /usr/include/scsi/sg.h to something else. After recompile
|
|
<BR>
|
|
sanei_scsi.c seems to use the kernel headers from /usr/src/linux
|
|
<BR>
|
|
(which are the right ones for my current kernel 2.4.5). I'm using
|
|
<BR>
|
|
Debian 2.2.
|
|
<BR>
|
|
<P>It doesn't happen if I use a SCSI controller with a queue depth of 2
|
|
<BR>
|
|
or more (e.g. Adaptec 2940) or if I disable double buffering in
|
|
<BR>
|
|
mustek.c. Double buffering means, that the backend sends two read
|
|
<BR>
|
|
requests to the scanner before waiting for the first one. So maybe
|
|
<BR>
|
|
this is a bug in queuing the commands sanei_scsi.c? It works if I use
|
|
<BR>
|
|
a 2.2 kernel.
|
|
<BR>
|
|
<P>Some parts of the debug log ans questions about it (color preview with
|
|
<BR>
|
|
a Paragon 1200SP). Questions/comments are marked with "---". The full
|
|
<BR>
|
|
logs are available on request.:
