>Description:
The following shell script, will sometimes cause a hard lockup, 
with keyboard lights not working, CTL-ALT-DEL not working, and a
garbled display. It will only happen once in a while, but it definitely
is the cause of the lockup:

#! /bin/sh

vidcontrol -b red yellow cyan
vidcontrol VGA_80x30
>How-To-Repeat:
Run the script multiple times.

 I applied the patch, and can not reproduce the lockup. I have tried many
 times. I am also able to use VGA_80x50 and VGA_80x60, which did not use
 8x8 font before the patch was applied.
 
 It sure looks good.
