Interrupt handling for *PCI boards with ASUS Sandybridge motherboards*
seems to be broken.

It has been seen with network and non-network PCI boards. PCIx network
boards work OK. And all reports are for ASUS motherboards.

It always results in the infamous "IRQ n: nobody cared" message usually
within an hour. It is possible to restart things by rmmod/modprobe on
the appropriate PCI driver.

Andrew Morton kindly took a quick look and thinks it is most likely an
ACPI bug.

Configuration summary:
- ASUS P8H67-V/R3 Motherboard (others have problems with similar M/Bs)
- M/B BIOS 0804 (just updated to that - no change)
- Core i5/2500K
- Onboard ethernet (at11c driver - works)
- Additional PCIx Intel ethernet board (e1000e driver - works)
- Additional PCI Broadcom BCM5702X ethernet board (tg3 driver - fails)
[ Also fails with other PCI boards such as RTL8139 ]
- Kernel 3.0.6


Any help much appreciated...


Does it help to boot with: pci=nocrs ?
