Can you share your FENRIS kernel config please ?

Hi, I have a T490 as well, I was running 13-STABLE and the previous fbsd13 kmod just fine for months. I upgraded to the latest stable last night, also had to move from the "fbsd13" port to graphics/drm-510-kmod and now acpi_video no longer provides any backlight knobs in sysctl. But anyway, at least Xorg works fine.
