Subject: [PROBLEM] ASUS Sandybridge motherboards + PCI not working (IRQ n: nobody cared)
Date: Fri, 14 Oct 2011 12:04:58 +0100 [thread overview]
Message-ID: <4E98175A.8040905@pobox.com> (raw)
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...
