The error,
klog: HIGH Kernel message: [ 0.240390] [Firmware Bug]: ACPI: No _BQC method,
cannot determine initial brightness
due to the kernel cannot find the ACPI _BQC method provided by firmware.
and the kernel log info,
klog: HIGH Kernel message: [ 0.286778] pnp 00:05: [Firmware Bug]: [mem
0x00000000-0xffffffffffffffff disabled] covers only part of AMD MMCONFIG area
[mem 0xf8000000-0xfbffffff]; adding more reservations
is due to the firmware device Device (MEM), report incorrect/unnecessary
resource.
These are both from the improper firmware and need to fixed by firmware.
