I see two notable things here:

- There is no sign of the i915 module being loaded, I guess the on-board
  graphics is disabled in the BIOS/UEFI?

- The boot seems to stall for 27 seconds.  That is probably unrelated to
  this bug, but if you want to find out why, systemd-analyze(1) is your
  friend.

No - I don't think I'll be able to solve the problem, but at least you
have an easy workaround.
