Quick fix 'NMI received for unknown reason 21 on CPU' on linux.

Errors:


pluto:~# dmesg |tail -n 3
[2061941.029736] Uhhuh. NMI received for unknown reason 21 on CPU 3.
[2061941.029779] Do you have a strange power saving mode enabled?
[2061941.029821] Dazed and confused, but trying to continue

The solution:


pluto:~# sysctl -w kernel.nmi_watchdog=0
kernel.nmi_watchdog = 0
pluto:~# echo "kernel.nmi_watchdog=0" >> /etc/sysctl.conf
