<i>&gt; &gt;</i><br>
<i>&gt; &gt; I'll be scanning some page and as the data is coming in the scanner</i><br>

<i>&gt; &gt; Mouse won't move, keyboard leds won't react, network connections don't</i><br>

<i>&gt; &gt; A hard reset is my only escape.</i><br>
<i>&gt; &gt;</i><br>
<i>&gt; &gt; I've got a HP ScanJet 5P scanner, attached to a BusLogic Flashpoint LT</i><br>
<i>&gt; &gt; SCSI adapter.</i><br>
<i>&gt; &gt; The adapter is SCSI ID 0. The scanner has ID 3. My harddisk (WD 9.1G) is</i><br>
<i>&gt; &gt; attached to this adapter aswell, on ID 1, as are my CDROM player</i><br>
<i>&gt; &gt; (Pioneer ID2) and my CDWriter(Plextor ID4).</i><br>
<i>&gt; &gt; All the other devices on the adapter function fine.</i><br>
<i>&gt; &gt;</i><br>
<i>&gt; &gt; I've got a PII-450 w/ 256 MB RAM and *PLENTY* of diskspace available.</i><br>
<i>&gt; &gt;</i><br>
<i>&gt; &gt; There's the option to modify a .h file in the kernel source tree to</i><br>
<i>&gt; &gt; increase the buffer size for increased speed. I've tried that (yes,</i><br>
<i>&gt; &gt; recompiled sane after changing the value) and it didn't bring me a speed</i><br>
<i>&gt; &gt; advantage, nor did it help put a stop to these weird lock-ups.</i><br>
<i>&gt; &gt; Recompiled sane after changing the values back again.</i><br>
<i>&gt; &gt;</i><br>
<i>&gt; &gt; I'm running Slackware Linux 4 which is still using libc5. I sincerely</i><br>
<i>&gt; &gt; hope that that's not what's causing the problems I'm experiencing.</i><br>
<i>&gt; </i><br>
<i>&gt; I have a machine with both a Buslogic 930LT and a 950, any attempt to use the</i><br>
<i>&gt; 930 locks up the machine tight. I have never been able to resolv this problem</i><br>
<i>&gt; with over a year of trying, yet the 950 (Ultra wide) which the drives are</i><br>
<i>&gt; connected to works fine.</i><br>
<p>
But don't you think it's weird that I can do several scans before it<br>
locks up (then it's 3, then it's 30, but it always does eventually) and<br>
yet no other device on the SCSI bus has a problem?<br>
Writing CD's at 8-speed without any complaints, heavy datatransfers from<br>
CD to harddisk aren't a problem either.<br>
It's *ONLY* happening when scanning.<br>
<p>
Basically you're saying that I should bring this issue up with the<br>
developer of the SCSI driver for my adapter or get myself a new SCSI<br>
adapter?<br>
