Hmmm. Pulled down 2.4, compiled it with gcc 2.7.2.1, '-O3
-fomit-frame-pointer -m486', executed 'crashme +2000 666 100 1:00:00 2'.

I don't know whether this is arrogance, but it's been running for 40 minutes
and, besides doing my usual stuff, am recompiling the kernel for the kicks.

I'm running on the 'best known' no-name brand PCI board, Triton I, P133
overclocked at 166, NCR810, but I do have EDO RAM.

This box ain't gonna crash. Must be the peltier that does it.

PS. 'crashme' just kicked out
