Killing interrupt handler without crash...

I just saw this message when doing my regular log reading. The
box is still up and running. Linux kernel is 2.0.30. Rest of
it is RedHat 4.0 (or 4.1, don't remember for sure).

Previously when "Aiee, killing interrupt handler" message has
appeared, that box has been needing wakeup with reset button.
This time nothing like that happened and I only had to restart
fingerd manually; the box didn't crash and is still running
smoothly.
