<i>&gt; Justin&gt; Since Linux/SPARC isn't listed on the Supported Platforms</i><br>
<i>&gt; Justin&gt; list at the sane website, I thought someone might be</i><br>
<i>&gt; Justin&gt; interested in this.</i><br>
<i>&gt; </i><br>
<i>&gt; Sure am! Thanks for the info. I updated sane-support.html as well as</i><br>

<i>&gt; </i><br>
<i>&gt; Justin&gt; Only problem relates to the sparc SCSI, not sane. While the</i><br>
<i>&gt; Justin&gt; scanner is moving and not scanning, the kernel vomits out a</i><br>
<i>&gt; Justin&gt; steady stream of:</i><br>
<i>&gt; </i><br>
<i>&gt; Justin&gt; esp0: Warning, live target 5 not responding to selection.</i><br>
<i>&gt; Justin&gt; (scanner is ID 5)</i><br>
<i>&gt; </i><br>
<i>&gt; Justin&gt; Also, once, the scanner froze the SCSI bus and the system</i><br>
<i>&gt; Justin&gt; eventually kernel panicked (root drive is on the same bus)</i><br>
<i>&gt; Justin&gt; ... but this happened once out of 20 or so successful scans.</i><br>
<i>&gt; </i><br>
<i>&gt; The driver may simply be a bit eager in timing out. It's not an</i><br>
<i>&gt; uncommon problem. E.g., we had the same problem with the ncr810</i><br>
<i>&gt; driver. You may want to check the driver for timeout constants that</i><br>
<i>&gt; may be related to what you're seeing.</i><br>
<p>
On the other hand, reducing the "strip height" should reduce<br>
performance, but allow things to complete successfully. If that<br>
happens, then, indeed, the timeout constants are at work.<br>

drunk. The man himself claims he slipped while walking the dog. 080897
