Hi,
I've got an SMP Athon system: Tyan S2466 motherboard (AMD 760MPX chip set)
with an OPTi Inc. 82C861 (rev 20) (prog-if 10 [OHCI]) PCI USB board. I'm
getting an oops trying to scan with an HP OfficeJet G85 connected to a USB
port. With kernel 2.4.18, the ksymoops output is (ptal-mlcd is the
OfficeJet's user mode driver):
Unable to handle kernel NULL pointer dereference at virtual address 000000c0
*pde = 00000000

I'd appreciate any help getting this working with the 2.4 series.
Thanks,
