<pre>[ 3.073989] [drm:pwm_setup_backlight [i915]] *ERROR* Failed to own the pwm
chip
You're missing some pwm/gpio stuff most likely from the kernel (or it got
loaded after i915).
Make sure you have at least these:
CONFIG_PWM=y
CONFIG_PWM_CRC=y
CONFIG_I2C_DESIGNWARE_PLATFORM=y
CONFIG_I2C_DESIGNWARE_PCI=y
CONFIG_INTEL_SOC_PMIC=y</pre>
