There was an email in the kernel list with a subject WSOD fix. in
December.

it contained link to this patch
http://git.openmoko.org/?p=kernel.git;a=commitdiff;h=43f0161295bc311d09d705db7b381653fbbb9e46

and the two scripts as per below.

i also suffer the recent WS issue and i haven't had too much to play
with this though, but perhaps it can help?


#!/bin/sh
# display_on.sh
echo 0 > /sys/class/graphics/fb0/blank
echo 0 > /sys/class/lcd/jbt6k74-lcd/lcd_power
echo 63 > /sys/class/backlight/pcf50633-backlight/brightness

#!/bin/sh
# display_off.sh
echo 0 > /sys/class/backlight/pcf50633-backlight/brightness
echo 4 > /sys/class/lcd/jbt6k74-lcd/lcd_power
echo 4 > /sys/class/graphics/fb0/blank
