panic during transition to multi-user mode _at_r249303 [i386]

I saw this first on my laptop; backtrace mentioned something about
iwn(4), so after I saved the crash dump, I flippe dthe wireless switch
off and tried again... and got a different (but undoubtedly related)
panic, which I also saved.

Then, after my build machine finished, that also got a panic (using a
GENERIC kernel), so I saved that away, as well.

Here's what's in there:

(I'm not too concerned about passwords being in there, since I never
had a chance to even try to type one in. :-}

Unfortunately, it appears that my invocation of "crashinfo" was
less than useflu, even though I pointed it at the kernel(s) that
had been running when the crash(es) occurred: the backtrace shown
is useless.  I can try to boot the build machine under the previous
"head" kernel (vs. stable/9), and try that again...?

AFK for a bit -- need to have laptop display replaced (unrelated).

Peace,
david
