It took a while, but I've finally managed to panic one of my machines.
It was rebuilding the entire system when it happened:

  cd /usr/src
  ./build -T /usr/tools -O /usr/obj -E build


The following is copied by hand:

uvm_fault(0xc034dec0, 0xcab74000, 0, 1) -> e

I also did a ps to find out what was running at the time of the crash.
It was rm.

See the previous email that I sent to see the dmesg for this machine.
