[BUG] Ksoftirqd and kworker use 100 percent of the cpu core

[Servet Portakal <servetportakal@gmail.com>]

Hello,

Ksoftirqd and kworker use 100 percent of the cpu core after resuming from the
suspend and the hibernation mode. For example;  Ksoftirqd/1 %42,
kworker/1:0 %29, kworker/1:1 %28.

I'm not an expert. nonetheless I tried to pick some
error messegas to ease your work.

On windows 7, suspend mode was not working when I open hybrid-sleep
mode. İt may help...

You know suspend mode is crucial for mobile devices. So I can't use
ubuntu regularly.
İf you solve this problem, I will be so delighted.

Best regards.
