#3547 closed defect (fixed)

unhandled IRQ in atheros 2.6 kernel

Reported by: flo@… Owned by: developers
Priority: normal Milestone: Kamikaze 7.09
Component: packages Version:
Keywords: atheros HP J9141A console Cc:


the atheros-2.6 target on an HP J9141A reports unexpected IRQs

unexpected IRQ # 0
irq 0, desc: 80271040, depth: 1, count: 0, unhandled: 0
->handle_irq():  800886d4, ->chip(): 80265c80, ->action(): 00000000

It seems these are console linked as when there is no action on the console you dont see any of these pop up. Also the DISABLED does not seem to work as the same IRQ comes over and over again.
