Just found in my logs with this command and still the same errors
dmesg|grep ERROR
[ 0.177668] acpi PNP0A08:00: _OSC failed (AE_ERROR); disabling ASPM
[ 372.223326] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun

The first error occurs always at the start of the laptop.
The second error occurs sometimes not always when i unplugged the hdmi cable connected to my tv.

For the functionalities, i suppose everything works fine on my laptop with the linux kernel 4.5 RC3.
