Compiling just the boot stuff in /usr/src/sys/boot/ (i.e., > without a bootstrapped gcc) results in a loader that works fine. Thus, I > think defining CPUTYPE results in a gcc that produces a bad loader. Mentioning athlon-xp sparked my interest... One of my systems is unstable under load when compiled with CPUTYPE?= athlon-xp, but not with i686. This typically manifests itself as segmentation faults or ICE errors at random places during compile jobs. The bootloader seems always fine however. regards, Derkjanhome | help
