 I'm not sure what you mean by world and kernel being sync'ed, I compiled
 the kernel and world like this.
 cd /usr/src/sys/i386/conf
 config OFL
 cd ../compile/OFL
 make -j9 cleandepend
 make -j9 depend
 cd /usr/src
 make -j9 buildworld
 make -j9 buildkernel
 make -j9 installkernel
 mergemaster -p
 make -j9 installworld
 I did a quick search on google on how to backtrace kernel but I couldn't
 find any information which pointed to what you are asking, could you
 please explain or provide a page which does.
 I also included make.conf though it might be useful.
 Regards, WS
