I find out that I just can't set the acpi_osi="!Windows 2012" properly

I did some experiment, I go to intel_backlight directory.
It show brightness is 4648, but actual_brightness is

Thanks Daniel
I am recompiling the kernel.
I will also open a bug in bugzilla when I collect all the relative information.
