Hello, I am affected by this bug too. I upgraded my Dell Studio from 10.04 to 12.04.1 and found this exact same issue while changing brightness.
Kernel that I am using -> 3.2.0-31-generic (64-bit). $ uname -a Linux neo 3.2.0-31-generic #50-Ubuntu SMP Fri Sep 7 16:16:45 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux If there is any additional details required, pls let me know.
