>Release:        2.8
>Environment:
	
	System      : OpenBSD 2.7
	Architecture: OpenBSD.i386
	Machine     : i386
>Description:
	i booted with the generic bsd kernel after upgrading to 2.8.  i logged in on ttyc0 as root, then switched to ttyc4, and logged in as a normal user.  when i switched back to ttyc0 everything was blue, ie the text.  i switched back to ttyc4 and all the text was red.  switching to ttyc0 again turned everything black.  i could reboot by typing reboot, but couldn't see anything until the system restarted.  it seemed to work fine if i didn't switch terminals.



>How-To-Repeat:
	as above.  it happened three times, every time.  i have a p200, 64mb ram, with a matrox millenium 1 and matrox millenium 2 graphics cards installed.  this happened using millenium 1, my primary card.	 i don't know if sendbug sends dmesg or not, but i can provide more info if you want.
>Fix:
	i booted again with a spare 2.7 kernel.  that's what i'm using now.  everything works again.
