Try building your kernel with 

options        DIAGNOSTIC
options        MALLOCLOG

and if you have lots of RAM to waste, it would be good to increase the
size of the dmesg buffer - MALLOCLOG can produce lots of output. I would
options                MSGBUFSIZE=1048576
Also, compile with makeoptions     DEBUG="-g" to aid any further
