I can confirm this bug also occurs for me. I have a Dell Inspiron N5010 running 12.04 64-bit. It occurs also when when adjusting the brightness well after the computer has started up, although it seems the most consistent way of reproducing the bug is to try to adjust the brightness in the first minute or so after logging in. Also, I have the laptop set up not to suspend when I close the lid. Closing and opening the lid only causes the screen to turn off and on, which can also trigger a complete system freeze. When the freeze occurs, it IS complete: CTRL+ALT+SysReq doesn't work, nor can I switch to a command line view with CTRL+ALT+F1.
