I am using debian wheezy... Cannot find a better discussion on this "Brightness Bug" in the whole world.... awesome effort here..
I have Dell Inspiron N5010 , Core i3, 4 GB RAM AND INTEL HD After updating to 3.2.xx the system starts hanging when the brightness was adjusted. I googled and found that it was a kernel bug. So i leaned how to compile my own kernel. NOW I HAVE 3.10.5 Kenel BUT TO MY SURPRISE THIS BUG WAS STILL DER..... :`-( But then more googling got me to this thread and MARWANS SOLUTION (NO. 71) WORKING FOR ME...
