I suspect it has something to do with SMP.
( i changed the SMP=1 to smp=0 in the toplevel makefile)

P6-233Mhz 64M 3.8EIDE 10mb/s ethernet

Debian 1.2.10
ii libc5 5.4.23-2 The Linux C library version 5 (run-time libr
2.1.37-4

When i start the machine it feels like is slow.

procinfo and/or top confirms this:

We participate on the DES challenge.
The provided Linux ELF binary dumps core on me:

None of these symptons show up using 2.0.30

Anyone has a hint ?
