Same configuration as before:

netbooted dual processor box, local /usr/obj, swap, and nfs-mounted
everything else.  World build -j 8.

crash1# make -j 8 buildworld >& /tmp/build.out

I believe the lock order reversal and the panic may not be related.
Unfortunately, the instruction pointer provided here does not appear to
correspond with any code, and I couldn't drop into the debugger so
couldn't get any more information.
