As far as I know, the problems are because egcs optimizes some things that
shouldn't be optimized, which in turn is because some volatile or barrier
instructions are Just Plain Missing. I.e., it's a kernel code problem.
Proof: EGCS-compiled 2.0 kernels generally work, until you push them with
"aggressive" networking or (some) device usage.
