Subject2.5.51 - Strange UP APIC / 8139too / USB issues
Hi all.

I have a system with an Abit AT7 motherboard: VIA KT333, single Athlon,
512M RAM, onboard RTL8139 network, USB, USB2, 1394. *NO* onboard PS/2
keyboard or mouse ports.
Other: IDE HD, CD-RW, and DVD. Radeon 8500DV (will try getting that
working later :)

I have used the system successfully with 2.4, and have been trying to
get 2.5 to work. Until now, I haven't been able to get the USB keyboard
to work. It is initialized by the BIOS, and is usable by GRUB for
selecting boot images.

I finally found the culprit - "Local APIC Support on Uniprocessors" and
"IO-APIC on uniprocessors". If both items are enabled, the network
functions, but USB doesn't work. If not both are enabled (neither, or
Local APIC but not IO-APIC), then the USB system works, but the network
doesn't. :(

I am not using modules.

these are the only differences in .config:

I can send complete configs, lspci / lsusb / whatever else anyone wants.
