Unfortunately, the KMS backlight support seems to use a significant
amount of CPU for each backlight level change. If you have
LCD_FadingSpeed and/or LCD_AutoAdjust enabled in /etc/pbbuttonsd.conf,

Maybe pbbuttonsd is confused because the backlight level range is
different than previously. Can you fix it up manually?
