Same bug here.

Just one strange thing:
Sometimes the Brightness Keys do work as intended, and sometimes they do not.

I have not yet figured out why.

When the Brightness Keys work my "dmesg | grep video" only shows:
[ 2.385961] ACPI Warning: _BQC returned an invalid level (20090903/video-631)

When the keys fail to work I have additionally:
[ 2.443136] ACPI Warning: _BQC returned an invalid level (20090903/video-631)
[ 6.540549] ACPI Error: Evaluating _BCM failed (20090903/video-528)
