--- Comment #7 from Kevin Bowling <kbowling@freebsd.org> ---
I don't think they need to be the same version, but you could revert the one
commit on the display system.  I've never used this though, so I can't vali=
date
that it actually works still.  But it seems worth trying to see if there is=
 a
useful panic string or whatever where the screen is going blank when debugg=
ing
is enabled, and you can also run kgdb remotely over it.

Otherwise maybe Nathan has enough context with your report now to take a lo=
ok.
