kernel panic with Friday -CURRENT

[Robert Huff]

	After cvsuping overnight and rebuilding Friday morning I
upgraded -CURRENT.
	Now I'm getting panics with:

Good dump found on device /dev/da1s1b
  Architecture: i386
  Architecture version: 1
  Dump length: 536854528B (511 MB)
  Blocksize: 512
  Dumptime: Fri Jan 30 22:20:04 2004
  Hostname: jerusalem.litteratus.org
  Versionstring: FreeBSD 5.2-CURRENT #0: Fri Jan 30 12:30:40 EST 2004
    huff at jerusalem.litteratus.org:/usr/obj/usr/src/sys/JERUSALEM
  Panicstring: kmem_malloc(-791617536): kmem_map too small: 30924800 total allocated

	I have the core dump; how do I extract the stacktrace?  (And
whot other useful information do I want to provide?)  "gdb -k"
claims not to recognize the file format.
