[Bug 49141] Re: ksoftirqd eats all cpu

[stephen84s]

I tried booting with the nohz=off setting and this is what I observed,

Initially after logging in, the CPU usage was perfectly normal,

However after a couple of hours, the laptop went into power saving mode due to inactivity and then when I resumed it,
ksoftirqd was back in action taking 80-90% of my CPU, 
following is the output of the "top" command in my terminal: -

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND            
    7   root        39 19     0    0         0  S  100     0.0         5:21.58 ksoftirqd/1
