        <pre>Marc, please attach intel_reg_dumper output from the intel-gpu-tools [1]
running 1) the bad commit b35684b8fa94e04f55fd38bf672b737741d2f9e2 and 2) the
(presumed good) commit immediately before it.

Running the good kernel, please also try to change the brightness by echoing to
the /sys/class/backlight/intel_backlight/brightness file - does it work as
expected? Does the dell_backlight work?
