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...
