After numerous kernel panics, I have concluded that my
Symbios card (Symbios Logic 53C400A) which is recognized
by the ncr53c406a driver (and kernel panics right after)
has seen better days. I'm not into debugging SCSI drivers
for ancient cards, so I'm retiring it.
I cried uncle and purchased an Adaptec SCSI card 2906,
which takes the AIC7*** driver and is PCI plug and pray.
After an uneventful kernel build and boot, the kernel
located both the card and the scanner. from there,
find-scanner worked and so did xscan-image.
Thanks for your help! When all else fails, toss the
crappy SCSI card. I think I'm the first Linux Chick
on my block to get her scanner working under Linux and
SANE.
