I don't use ACPI (should I ?) but have the same problem with my
ECS K7VTA3 5.0C and the onboard Realtek or a 3Com 3C905CX-TXNM,
although I had and still have other problems without IO-APIC,
like modprobe bttv instant freezes when USB 2.0 shared the same
IRQ. To "solve" I moved the card to another slot.

The problem is that loading USB without IO-APIC still gives
instant freezes. I first experienced it with bare.i from
Slackware 9.0 and SuperRescue 2.1.1, which stop at

hcd.c:ehci-hcd@00:10:3,VIA Technologies, Inc. USB 2.0

, and later doing the usual modprobe with 2.4.2{0,1}.
I just tested with 2.4.21. With IO-APIC everything worked
except the ethernet. Testing USB:

# modprobe usbcore
usb.c: registered new driver usbdevfs
usb.c: registered new driver hub

# modprobe usb-uhci

Without IO-APIC (noapic boot option) modprobe usbcore worked,
but modprobe usb-uhci freezed after printing

usb-uhci.c: $Revision: 1.275 $ time 01:28:00 Jun 14 2003
usb-uhci.c: High bandwidth mode enabled
PCI: Found IRQ 11 for device 00:10:0
usb-uhci.c: USB UHCI at I/O 0xd400, IRQ 11
usb-uhci.c: Detected 2 ports
usb.c: new USB bus registered, assigned bus number 1

I'm starting to think there's something wrong with the
motherboard as the BIOS couldn't locate my Sound Blaster Live!
5.1 in any slot. I think I tried everything, also disabling all
onboard options, RAID, and FireWire. At the end I just sold it
and am now using the onboard sound.

USB works on Windows XP Professional SP1 (I could only test a
game pad) along with the ethernet, and I didn't have to move
the capture card to get it working there. I moved it to get it
working on Linux.

I uploaded my 2.4.21 .config, /proc/{ioports,interrupts,pci},
and the last 4 dmesg just in case someone is interested.

BTW, what does noapic do when you enable all APIC options and
when you don't enable IO-APIC ?
