Backing out this commit (with a slight conflict in /sys/sys/kernel.h) allows my box to build an up-to-date -stable world is less than 5 hours (instead of 20) again. Any chance someone with i386/smp-foo can look at this? Original message at: http://docs.freebsd.org/cgi/getmsg.cgi?fetch=3D33169+0+archive/2001/freebsd= -smp/20010930.freebsd-smp --=20 Chris D.
