-m 512 ?  Hmm did you increase kern.maxdsiz for that?  Since the
default is 512M, and qemu needs memory for itself too...  (tunable
in loader.conf.)  Or, failing that, try smaller -m args, like 256.

 Oh, panic, not lockup?  Can you get a backtrace?  (see
	http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug.html
, i.e. do a script(1) log of `bt' in kgdb.)
