System: FreeBSD Coryphantha.DOMO.SVA 4.7-STABLE FreeBSD 4.7-STABLE #238: Tue Jan 21 22:28:41 CET 2003 root@Coryphantha.DOMO.SVA:/usr/obj/usr/src/sys/Coryphantha i386
vt0 on isa0
vt0: generic, 80 col, color, 12 scr, mf2-kbd, [R3.20-b24]
vt0: driver is using old-style compatability shims
>Description:
If you configure the pcvt driver with the option
COLOR_KERNEL_FG=FG_YELLOW
(or another color with value greater than 7, see
src/sys/i386/include/pc/display.h),
and load a second character set, then the kernel messages
become illegible in console.
>How-To-Repeat:
Install a kernel with the pcvt driver and with the options
COLOR_KERNEL_FG=FG_YELLOW
COLOR_KERNEL_BG=BG_BLACK
Then from a terminal:
loadfont -c0 -f /usr/share/misc/pcvtfonts/vt220l.816
loadfont -c1 -f /usr/share/misc/pcvtfonts/vt220h.816
scon -s 25
shutdown -h now
