    No. I've seen many oopses which were completely harmless (few
    processes died, who cares? :-).

    I advocated putting 10sec delay after oops. It is good so at least you
    can see the oops and you can remeber IP if you are fast enough
    ;-). Much better than quickly rebooting machine. If you extend this
    delay to 10min, user will have plenty of time to copy data onto paper
    ;-)))).

    Unfortunately, there were cases when this destroyed valuable data.
