System: FreeBSD guru.mired.org 5.3-STABLE FreeBSD 5.3-STABLE #12: Wed Dec 15 18:22:07 CST 2004 mwm@guru.mired.org:/usr/src/sys/i386/compile/GURU i386


>Description:
	When booting a kernel that uses the sc device for a console,
and either VGA_NO_FONT_LOADING or SC_NO_FONT_LOADING enabled and
running an xdm on one of the VTYs, the non-X vtys come up with no
visible font. Further, on shutdown the console is garbaged.

I have no idea if this problem happens or not if you fail to start an
X server. It may not.

>How-To-Repeat:
	Build a kernel with either of those two options enabled, boot
	it, and run an X server. Then switch to a different vty, and
	observe that you either get garbage on the screen, or that no
	characters are printed.


>Fix:

	The work-around is to not enable those two options. I haven't
	had time to look into fixing the problem, but will if I find
	the time.
