Hm, could be another patch if we run into it. Newbyte (CC) has tested
it and it works fine and stabilize his system without any problems in
practice with the backlight setting. I would say if users run into this
issue we can look into a timeout-and-restart loop.

You can add:
Tested-by: newbyte at disroot.org
after discussion on IRQ.
As this makes things not crash at least.
