I tried the drm-intel-nightly kernel (from 18 June) and still experience the same problems as originally reported. I followed the steps in comment #31 to attach logs - those logs attached. The failure with these logs was slightly different though - behaviour was that I could see the login prompt, but no keyboard input was recognised - i.e., the same thing that I saw in comment #32. So sometimes failure is that I can't get to a screen with the login prompt and sometimes the failure is that the login prompt is there but I can't actually log in because keyboard input not recognised/processed.
