Excerpts from David Santamauro's message of 2010-08-24 14:10:12 +0200:
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
A few BIOSes allow that, plugging it into another slot might help as
well. I'm not sure there is a software way to do it. I'm not sure
whether the rtirq script does something like that or just changes
priorities.
