Hi All,

Can someone clarify me what is âNMI injectionâ means? Does it helps
when system is frozen? If so how to do this for Intel Atom processor
machines?

I configured my system to respond for SysRq key press, but I see when
system is frozen then SysRq key press has no effect.

Iâve read that when kernel is locked up it wonât respond for SysRq key
press actions.

What is the definition for âkernel locked upâ means? And how to solve this?
