Вчера пересобрал ядро. Никакие параметры поддержки драйвера WMI не менял. Получил:
boot.log
Starting Backlight.service...
Starting Backlight.service 1mfailedm, see systemctl status Backlight.service for details.
systemctl status Backlight.service
Backlight.service

Раньше работало, хоть и костыльно.
Идеи?
