<i>&gt; &gt;Is this command a "lockup-always" on your system ? Or does it work from time </i><br>
<i>&gt; &gt;to time ?</i><br>
<p>
<i>&gt; Well, I haven't tried it too often, but in most, not all, cases it locks up.</i><br>
So it sounds this is a timing-related problem. I have an old 486DX/33 attached<br>
to the scanner, so maybe it is slow enough most of the time ;-).<br>
<p>
<i>&gt; &gt;Moreover please note, that -l,-t,-x,-y might be ignored because the mode-set</i><br>
<i>&gt; &gt;command might override these values.</i><br>
<p>
<i>&gt; They actually seem to be accepted, but that shouldn't change the result anyway.</i><br>
<p>
Well - they are accepted, but in my case, they are ignored and the whole area<br>
is scanned when it works. This is a "known feature".<br>
<p>
<i>&gt; Does it still lock up when you change the mode to Gray? </i><br>
Haven't seen that happen. Maybe it does, too, but it is quite infrequent, then.<br>
<p>
<i>&gt; Here, it still does, but not that often (much less often, indeed).</i><br>
<i>&gt; How big is your SCSI buffer?</i><br>
32K. Unchanged, standard kernel.<br>
<p>
<i>&gt; Where does the scanner stop? (ruler on the scanner)</i><br>
At 0. The scanner does its "calibration move" and that's it.<br>
<p>
<i>&gt; I don't have any idea what could be the problem.</i><br>
I suppose some timing problem ...<br>
