I am getting the same with my Asus K8V-VM system. The interesting thing is that IRQ 23 is my on board Ethernet card, and it gets disabled after 100001 interrupts. It seems like the incrementation of the interrupts on the Ethernet controller aren't due to network traffic but rather from the interrupt activity of my Nvidia graphics controller on IRQ 24.
This problem can be avoided by adding noapic to the kernel command line, but in this case, the system is slightly slower and I get a high number ERR: in /proc/interrupts Attached are the dmidecode and lshw outputs.
