[LAU] irq sharing

Hi,

I've decided to get back to diagnosing why my delta 1010 inputs have a
background noise and stumbled across a few websites indicating that the
problem could be irq sharing.

My delta shares irq 20 with usb devices:

$ cat /proc/interrupts |grep ICE
  20:    1325915    1326971    1335010    1348560    1337725
1330100    1336582    1346152   IO-APIC-fasteoi   ehci_hcd:usb1,
uhci_hcd:usb2, ICE1712

Is there a way to forcibly assign ICE1712 to another IRQ? I just want
to test the theory.

thanks

David
