Subject: which is the cause of interrupts
Date: Sun, 3 Jun 2007 00:50:47 +0200 [thread overview]
Message-ID: <20070602225047.GL30199@vanheusden.com> (raw)
Hi,
Powertop 1.5 tells me:
Wakeups-from-idle per second : 1161.0
no ACPI power usage estimate available
Top causes for wakeups:
49.3% (898.0) <interrupt> : ehci_hcd:usb1, uhci_hcd:usb8, wcfxo
20.1% (366.4) <interrupt> : ide0
7.4% (135.0) bot : schedule_timeout (process_timeout)
Now how can I find which device is triggering those "ehci_hcd:usb1,
uhci_hcd:usb8, wcfxo" interrupts?
