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
