Summary: IRQ Nobody Cared on Sandybridge Additional Ethernet Card Product: ACPI Version: 2.5 Kernel Version: 2.6.39.2 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Config-Interrupts AssignedTo: acpi_config-interru...@kernel-bugs.osdl.org ReportedBy: chris.pal...@pobox.com Regression: No Created an attachment (id=64232) --> (https://bugzilla.kernel.org/attachment.cgi?id=64232) /proc/acpi/wakeup Additional PCI ethernet card in Sandybridge M/B runs for a few minutes, then gets IRQ 19 Nobody Cared System details: - Asus P8H67-V/R3 (latest Bios 0712, default settings except AHCI and VT-enabled) - COREi5/2500K - 4 x 4GB Corsair CMX8GX3M2A1333C9 - On-board video and ethernet (eth1, at11c driver) - One additional RTL8139 or Broadcom BCM5702X PCI ethernet for eth0 (fails identically with either) - no other cards - FC14 with 2.6.39.2 custom kernel, updates to 30/6/11 Moving to another slot only changes the IRQ number involved. The following do not prevent the problem: - pci=noacpi - acpi=noirq - noapic - nolapic - pci=nocrs Setting acpi=off does appear to prevent the problem (at least it runs for a couple of hours...) but is undesirable as power consumption is about 25% higher, and the CPU temp is markedly higher even with the CPU fan running faster. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable.
