My computer is currently doing something like 30k+ interrupts per second. This causes battery issues as well as the CPU being always stuck at the highest speed, making it very hot (overheating.. 75C at IDLE)

Powertop info:

99.4% (32052.4) [acpi] <interrupt>
0.3% (115.9) [iwlagn] <interrupt>

Just to clarify this started suddenly a couple of days ago. It didn't have this issue before (though I had a tonne of headaches with Linux on my computer in general..)
