Bug Description
Binary package hint: linux-generic
in 10.04 I've noticed my laptop overheating.
Upon checking powertop I noticed these two in the top :
38.7% (419.8) [Rescheduling interrupts] <kernel IPI>
11.1% (120.8) [kernel scheduler] Load balancing tick
My system acts this way (fans full throttle, cpu at big temp) while IDLE-ing
This does not happen in 9.10 nor windows OS.
