please help: usb and irq problem with 2.2.18 and 2.4.0-test?

i've asked a few times, both off-list and on and nobody seems to be able to help.

quite a few people are seeing usb fail (with the "device not accepting new address" error messages) on the 2.2.18 and 2.4.0-testX kernels with smp enabled when using a mobo with the apollo pro 133a chipset. when apic is disabled, everything works, but with it enabled, it seems that the usb driver (usb-uhci) is not getting any interrupts. johannes erdfelt thinks that it's a pci irq routing problem (/proc/interrupts is showing no interrupts for usb-uhci when apic is enabled) and suggested talking with the pci irq people.

i eager to help debug this problem and apply any and all test patches to find fixes. i am pretty sure that greg k-h (greg AT kroah DOT com) is also willing to do the same. the problem is, we can't get any pci irq people to look into this. is this a problem with the pci irq routing? is this a known problem that someone's working on? is it just not worth the effort? there are already quite a few people on the linux-usb list who are seeing this problem. i'm sure that when 2.4.0 comes out, a lot more people will be seeing this problem too. please, let's try to stomp this out before 2.4.0 and make linux look just that little bit more shiny. =8]

(sorry for that bit of a rant, but i'm getting just a little bit frustrated with this long-standing problem.)

thanks,
pete
