Hello, it seems the new linux image package from experimental linux-image-5.4.0-trunk-amd64 does not exhibit the GPU initialization failure problem.
boot log for this kernel version has: [ 2.405213] i915 0000:00:02.0: VT-d active for gfx access [ 2.405347] i915 0000:00:02.0: vgaarb: deactivate vga console [ 2.425755] i915 0000:00:02.0: vgaarb: changed VGA decodes: olddecodes=io+mem,decodes=io+mem:owns=io+mem [ 2.426608] i915 0000:00:02.0: firmware: direct-loading firmware i915/kbl_dmc_ver1_04.bin [ 2.427067] [drm] Finished loading DMC firmware i915/kbl_dmc_ver1_04.bin (v1.4) [ 2.443913] [drm] Initialized i915 1.6.0 20190822 for 0000:00:02.0 on minor 0 [ 2.467784] fbcon: i915drmfb (fb0) is primary device [ 3.623962] i915 0000:00:02.0: fb0: i915drmfb frame buffer device regards, Bart.
