Ok, I commented without checking the dmesg log properly. Please retest using
the latest firmware:

[    3.706008] [drm:intel_csr_ucode_init] Loading i915/skl_dmc_ver1.bin
[    3.707891] [drm] Refusing to load old Skylake DMC firmware v1.22, please
upgrade to v1.23 or later
[https://01.org/linuxgraphics/intel-linux-graphics-firmwares].
