Maybe not the same, but could be related:

I think there is some basic problem with shared interrupts.

I have tried everyhthing I could to diagnose it further, looking
for culprits in the ath driver and the auich driver (those two share
interrupts in my case), but I haven't found anything. I lack i386 low
level and/or acpi skills, so this is probably beyound me.

Maybe this should be added to the "critical bugs to fix for 4.0" list?
