3.6.11.6 stable review patch. If anyone has any objections, please let me know.
------------------ From: Alex Hung <alex.h...@canonical.com> [ Upstream commit fedbe9bc6fd3e14b1ffbb3dac407777ac4a3650c ] On HP m4 lapops, BIOS reports minimum backlight on boot and causes backlight to dim completely. This ignores the initial backlight values and set to max brightness.
