Hi Folks.
I'm running a RH8.0 system, custom kernel on an Abit KA7 mobo. Trying to
use a Microtek V6USL scanner over USB. I've had the same problem on an
older kernel -- 2.4.7, I think.
Based on the web and mailing list archives I've searched, it appears to be
a common problem, but I haven't found any mentions of whether there's a
patch available, or if it's fixed in newer 2.4.x kernels.
I've transcribed the console output, and run it through ksymoops, but I
don't see the details in the oops report typical of other bug reports I've
read -- probably the bad transcription on my part. I did make sure I had
the same modules loaded when I ran ksymoops. Nonetheless ...

Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.

Any advice appreciated. There's a remote possibility I can run a serial
console, if I can find a null-modem cable -- unfortunately, I tossed out
nearly all my DB9/DB25 stuff a while ago, and any of it which remains is
in a box -- somewhere ...
