Origin of a kworker-thread

Question

On my newly installed system using kernel 3.2 I see a kworker-thread which is constantly consuming CPU. I\'d like to find out which part of kernel/module has created this workqu

Answer 1

So, after some time I found the solution. In fact Anthon is right, it is the ACPI-subsystem which sends interrupts. On my system I disabled the following interrupts and the kworker-thread is calmed down.

echo disable > /sys/firmware/acpi/interrupts/gpe1B
echo disable > /sys/firmware/acpi/interrupts/gpe08

However until now haven't identified what the bogus IRQs coming from gpe08 and gpe1B.
