Hello,

I have a new motherboard based on Intel H77, it's an Intel DH77KC. I needed to
use an extra ethernet card, tried three different PCI cards, but none of them
worked. It appears the driver is not receiving any interrupts. /proc/interrupts
shows only zeroes for "eth1".

This causes the interface to have the NO-CARRIER flag even when mii-tool
reports that a connection has been negotiated. And of course, the interface
doesn't work.

What helps? Only acpi=off, other options either don't help or make the system
unbootable. Turning ACPI off is however not acceptable as it disables all other
CPU cores but the first one.

Lubos
