Re: IRQ conflicts on 3c905c-tx

I'm using an Asus A7V333 motherboard, which is between 1 and 2 years old.
As best as I can tell, here's what's using the IRQs:

IRQ 5:  ata raid controller, usb controller, 3c905C-TX nic
IRQ 10: audio controller, firewire controller, usb controller
IRQ 11: usb controller, agp video controller (on a different bus?  does that
matter?)

I was only focusing on the nic problem, but now that I look closer at dmesg
output, it looks like there's all sorts of interrupt problems...perhaps I'm
chasing this problem in the wrong forum. Please accept my apologies if
that's the case.

Just in case anybody here has seen this before, however, I've attached dmesg
and lspci output below.
