Jan 16 07:03:23 server kernel: Disabling IRQ #177

In case again anyone is interested.

I just tried updating the bios, if it freezes again I will boot with acpi=off and then retest.

Issue still persists, anyway I thought I'd let you guys know in case someone is thinking about getting one or more of these boards.

Hi,

There does not appear to be a 'Plug and Play OS' option in the BIOS like on previous Intel motherboards.

I have disabled all of the USB ports except for the rear panel ones and so far it has been running for awhile.

I will see what happens.

thanks,

>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?

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?
