I see that there is a way to force a system crash from keyboard.

But does this work when the system is hard hung? i.e, when the keyboard is not responding?

Just because you hit keys and nothing happens doesn't mean the keyboard is not functional. There is a major difference in how the signal from a USB keyboard and a PS2 keyboard travel. In that respect, it makes a difference on exactly what caused the hang. In most cases, you'll always have a better chance of a PS2 keyboard getting a signal through. – MaQleod Dec 11 '12 at 1:24
Oh Ok. I was using a USB keyboard. And it did not help when I tried to force the crash during hang. May be I should try a PS2 keyboard if that helps here. – user682765 Dec 11 '12 at 1:34
