Linux Kernel 2.6.37 Backlight Problem

If you are using Intel Graphics Card and planning to build Linux Kernel 2.6.37 on it, you probably want to postpone it a little bit, especially if you are using the Power Management feature on laptops. It says that 2.6.37 has some backlight problem and Linus and Chris Wilson were trying their best to fix the problem, but at the end, there were some bugs left and it has been reported by Michael Hocko at this LKML thread.

Chris has offered a patch, but it didn't fix the bug fully, so it's still an open bug for now. I think we will have to wait until Greg managed to launch his -Stable release after a while.
