Ok, so nothing yet on the screen seems to suggest either a graphics-related issue or a different, early problem.
The successful test to boot into recovery mode provides a very good lead; thanks for coming up with that. These are the 3 kernel options added by the recovery mode, per the kern.log file you attached: 'recovery nomodeset dis_ucode_ldr' - nomodeset is graphics related, and - dis_ucode_ldr is processor microcode related, which runs very early. which supports that theory. So please try booting with either one of them, (please remove quiet and splash, no more earlyprintk nor ignore_loglevel.) I imagine that nomodeset is more likely to do the trick. If dis_ucode_ldr does it, there's something worse in it. If you need _both_, I'd be surprised, as they're not related. Thanks!
