--- Comment #25 from zeng.shixin at gmail.com ---
Problem still exists with 4.5.1.

>From the kernel log, I see a line:

Feb 19 02:52:00 winbook7 kernel: [drm:pwm_setup_backlight [i915]] *ERROR*
Failed to own the pwm chip

which is mentioned in bug report
https://bugs.freedesktop.org/show_bug.cgi?id=85977

I also tried to blacklist i915 when the system boots up and then to manually
load the module to avoid the timing issue that PWM might come after i915 is
loaded, but to no vail.
