[c-nsp] Can "power-on" mean anything other than power on?

[Sukumar Subburayan (sukumars)]

Please ignore "Last reset from warm-reset". It is bogus, and should not
be trusted. 

There is a software fix (in rommon) and IOS, which fixes this reset
reason correctly.

Since, 3 boxes rebooted all at the sam time, I agree with others that
this is most likely a power related issue.

I'm no genius, but "Last reset from warm-reset" indicates to me there
was no power loss.
