currently attacking the box with a flood ping. I used a pristine 2.4.1.
to be sure I didn't leave stuff and applied the patch.

observations -- system doesn't crash; usually I had to use disable focus
processor -- else it fails.

other observations -- approx 6000 ints from the ne2k card/sec.
MIS shows approx 1% that goes wrong with a ping flood.
