/sys/i386/conf/NOTES says:
# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32
# machines. VmWare seems to emulate this instruction poorly, causing

So, you'll need to rebuild a new kernel on another system with:
options CPU_DISABLE_CMPXCHG
and copy it into the virtual machine in order to boot normally.
