Not related.

For iwm:
  http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/sys/mbuf.h

Commit 1.164 broke iwm (and I guess all other wifi drivers)
and commit 1.165 fixed it.

For wm:
  http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/dev/pci/if_wm.c

Commit 1.413 broke wm and commit 1.414 fixed it.

- Jun 10 13:31:45: mbuf.h r1.164
- Jun 11 ??:??:??: you encountered the first panic
- Jun 12 10:14:12: mbuf.h r1.165
- Jun 14 09:07:22: if_wm.c r1.164
- Jun 14 ??:??:??: you encountered the second panic
- Jun 14 17:09:20: if_wm.c r1.165
- Jun 16 ??:??:??: you are here

And I noticed that I forgot to bump the kernel version; my mbuf.h
change required it. (I already bumped.) If you run a kernel between
my mbuf.h change and the bump with network device driver modules
of 7.99.30, something bad will happen. (I guess the issues you saw
aren't related to this though.)
