I take it that you didn't bother to read my original post. I was talking about a
computer hanging while processing an interrupt with interrupts disabled. Not
something that's likely to happen because of a simple page fault or other error,
or even at all.[1] Think of it as a black swan: something that's not supposed to
exist, but does, once in a great while. Fixing it doesn't require a BIOS reset,
just restarting the computer, and under the circumstances, that generally
requires[2] pulling the plug.
[1]That's the type of bug that's supposed to be swatted before the BIOS goes
into production.
[2]or did back when I was on the phones
In today's terms with the momentary contact ON button the OFF feature, unless
disabled in the BIOS, will turn it off after 2 to 5 seconds camped on the
power button. As long as that is enabled in the BIOS it will perform a hard
shutdown. Of course, if the heart is racing sometimes it is wise to tell the
poor victim, hold it in for 30 seconds or until the computer shuts down. 5
seconds can often seem like an eternity. (Yes, I have met at least one BIOS
that had a "what do I do with the power button press" that could disable the
hard reboot.)
