Only for information:

For me it is the same. I'm running xen-unstable of today with kernel
2.6.16-xen. Standard config of xen. (Its a DualXeon EM64T)

/proc/interrupts:
          CPU0       CPU1       CPU2       CPU3
18:     100000          0          0          0        Phys-irq
uhci_hcd:usb3

dmesg:
irq 18: nobody cared (try booting with the "irqpoll" option)

Call Trace: <IRQ> <ffffffff80151a80>{__report_bad_irq+48}
