CentOS - Jan 2011 - Intel DH67BL + CentOS 5.5 IRQ #177 nobody cared

Hello,

We have built a couple of CentOS 5.5 systems on the Intel DH67BL (Sandy Bridge)
motherboard and overall they work pretty well.

I'm having one problem which keeps cropping up and that is an error message
that says:

IRQ 177 nobody cared (try booting with the irqpoll option)
report bad irq, references CPU idle

then it references usb_hcd_irq and e1000_intr
then it disables the add-on PCI E1000 card and disconnects itself from the
network.

I'm assuming what is happening here is the USB controller and the add-on
E1000 controller we put in are having an old school IRQ conflict, the question
is why and how can I avoid it?

I have tried disabling all of the extra stuff in the BIOS that I could, and this
still happens fairly frequently.

Any advice would be great.

thanks,
-Drew

Have you tried putting one of the cards in a different slot?

Ah, it is a PCI card and there is only one PCI slot..

Hi Drew,

Hello, 



We have built a couple of CentOS 5.5 systems on the Intel DH67BL (Sandy Bridge)
motherboard and overall they work pretty well.



I'm having one problem which keeps cropping up and that is an error message
that says:



IRQ 177 nobody cared (try booting with the irqpoll option) 

report bad irq, references CPU idle 



then it references usb_hcd_irq and e1000_intr 

then it disables the add-on PCI E1000 card and disconnects itself from the
network.



I'm assuming what is happening here is the USB controller and the add-on
E1000 controller we put in are having an old school IRQ conflict, the question
is why and how can I avoid it?



I have tried disabling all of the extra stuff in the BIOS that I could, and this
still happens fairly frequently.



Any advice would be great. 



thanks, 

-Drew

 Have you tried what the error message suggests (add irqpool to the
kernel line in grub.conf) ?

Radu

IRQ177 means you are using APIC, which gives you over 250 interrupts - far
more than there were in the olden days. There should be enough that nothing
has to share IRQs.

 

But even before APIC came along, devices had gotten pretty good at sharing
IRQs. 

 

As someone suggested, disable the Plug and Play option in the bios. Try a
different brand of Ethernet card?

Can you disable the video card's use of an IRQ?  I've seen that before,
where the video card had an IRQ whether the driver needed it or not.

If you use a DVI to VGA/analog adapter and unplug an analog monitor, does it
still happen?
