Re: USB doesn't work with 440MX chipset, PCI IRQ problem?

I reported a similar problem. In my case, the interrupt
sharing is between two Cardbus cards (3c575 and a Belkin
BusPort Mobile). My network locks up with eth0 errors.
So, do you believe this is the same bug or something else?
My machine seems to be sharing the interrupt to four devices?
