DetailsDescription:
Powertop reports in excess of 20k interrupts a second since upgrading to kernel 3.2.12 96,6% (21546,0) [acpi] <interrupt> ar This completely trashes battery lifetime and forces my loud fans to spin up :( dmesg shows the kernel disabling PCI interrupts periodically [ 156.986153] uhci_hcd 0000:00:1a.0: PCI INT A disabled [ 156.986434] uhci_hcd 0000:00:1a.1: PCI INT B disabled [ 156.986779] uhci_hcd 0000:00:1a.2: PCI INT C disabled [ 156.987091] ehci_hcd 0000:00:1a.7: PCI INT C disabled I'm sure this must be some kernel regression, but I file this for other Archers that may experience the same behaviour. |
