Well ... I have had 4.0_STABLE/i386 (not SMP) panic when I
enabled jumbo frames on wm0.  I was making a bunch of hardware
changes at the time and running with a GENERIC kernel for
which I hadn't disabled ddb and awkward console access, so I
don't have crash dumps or even stack traces.

Because of all the other changes I was making I didn't know
what was at fault, but the other changes are still present and
running wm0 without jumbo frames my system is stable.  (My
memory says the panics were in virtual memory code, not the wm
driver itself, for whatever that's worth.)

I plan to rebuild 4.0_STABLE and retest, but I've been as so
often overrun by other projects and "if it ain't broke, don't
fix it" inertia, so no promises. :-(
