since installing the entry.S+process.c patches to cure the "UP flu", i
successfully ran a few different versions of my fork-test, so congrats
on the fix!
unfortunately, i've also experienced two spontaneous reboots and one
more oops that i haven't seen before (i've only been running devel
kernels since 2.1.125, though). at least one of the spontaneous
reboots also displayed an oops, but i couldn't read it fast enough.
here's the oops that actually caught, followed by the boot sequence.
if you would like more information, please just drop me a line. i'm
running a stock 2.1.129 kernel + entry.S/process.c patch for up flu +
tulip.c v0.90
