USB stops working on two _different_ pc's. Worked fine with 2.6.2.

Hi,

quite often I get this message in my dmesg:

irq 10: nobody cared!
Call Trace:

Disabling IRQ #10

I always have a round number of interrupts on irq10 when this happens:

           CPU0       CPU1       
  0:    1815656        248    IO-APIC-edge  timer

And obviously, usb stops working after this. This happens quite often,
on two _different_ motherboards. (both SMP). Earlier USB had irq 5, now
I have these lines:

PCI: Via IRQ fixup for 0000:00:11.2, from 5 to 10
PCI: Via IRQ fixup for 0000:00:11.3, from 5 to 10
PCI: Via IRQ fixup for 0000:00:11.4, from 5 to 10

Have no idea if this matters. Hope someone could help me sort this out.

Best regards,
Stian
