No change even after a fresh buildworld (using RELENG_6): cvsup /etc/supfile-src && rm -r /usr/obj/* && cd /usr/src && make make && make clean && make cleandir && make cleandir && make buildworld && make buildkernel && make installkernel && make installworld && mergemaster I don't mind leaving the option in the kernel, but it does seem like a strange bug. Let me know if anyone has any other ideas. Thanks, -John
