It seems MCA capability is advertised by the CPUID translator but writing to the MSRs causes GPF. In other words, it seems like a CPU emulator bug. A simple workaround is 'set hw.mca.enabled=0' from the loader prompt. If it works, add hw.mca.enabled="0" in /boot/loader.conf to make it permanent. MCA does not make any sense in emulation any way.
