<i>&gt; &gt;</i><br>

<i>&gt; &gt; It's *ONLY* happening when scanning.</i><br>
<i>&gt; &gt;</i><br>
<i>&gt; &gt; Basically you're saying that I should bring this issue up with the</i><br>
<i>&gt; &gt; developer of the SCSI driver for my adapter or get myself a new SCSI</i><br>
<i>&gt; &gt; adapter?</i><br>
<i>&gt; </i><br>
<i>&gt; Did you say what kernel you were using? I have a similar problem with my</i><br>
<i>&gt; BT958... I'm thinking this is likely a sg driver issue though. Anyways,</i><br>
<i>&gt; I'm going to overhaul my hardware... I have an odd motherboard and am</i><br>
<i>&gt; using software raid. I'm grabbing a AMI MegaRAID controller, replacing</i><br>
<i>&gt; the motherboard, and then I'll see how the BT958 fairs with a stock</i><br>
<i>&gt; RedHat 6.0 kernel. If it turns out to be the BusLogic controller I'll</i><br>
<i>&gt; have to see about swapping SCSI cards for the scanner... I think that</i><br>
<i>&gt; cheap AHA-1505 that came with the scanner works with the aha152x driver.</i><br>
<p>
I've had this problem occur in kernels as old as 2.0.26 and as recent as<br>
2.2.10.<br>
If it's an sg problem I'm inclined to think it should happen on other<br>
setups aswell, but since I haven't heared anybody else bring this up, I<br>
guess it's a BusLogic-only problem.<br>
<p>
Leonard N. Zubikoff, creator of the BusLogic driver, has remained<br>
unresponsive to my pleas for help.<br>
<p>
<i>&gt; Right now this problem is greatly hindering my ability to do SANE</i><br>
<i>&gt; related development.</i><br>
<p>
Well, this is greatly hindering (i.e. making it impossible) my ability<br>
to scan *AT ALL*!<br>
It's reached the point where I can reliably make the machine Oops during<br>
a scan.<br>
If anybody has some good hints on how to trap all that output that flies<br>
across the screen so I can submit it to developers that know how to deal<br>
with it, I'm all ears.<br>
<p>
And, like you, I'm getting myself a new SCSI adapter *JUST BECAUSE OF<br>
THIS*.<br>
I shouldn't have to, but if the developer seems uninterested and I'm<br>
uncapable...<br>
