I can confirm this on Toshiba Sattelite Pro U200. Until Xorg is started,
changing brightness works as expected. When Xorg starts, it's like every
time i change brightness, system does dpms off. If I keep pressing
Fn+F6/7, eventually screen will appear again.
In my case, Xorg doesn't crash, it
Obviously, this is a confirmed bug. It's caused by kernel module with X

Last comment for now:
The crash only occurs when the brightness is increased using the Fn-HOME
combination. If I adjust the brightness in any direction via
/proc/acpi/ibm/brightness, I get the correct Gnome on screen indicator
