Lino, are you going to provide a kernel output so I could look at your new breakage? If you could set up a pstore logger with a ramoops region, you could dump the log after the fact. Or if HDMI is all you have, you could use an HDMI capture card to record it. Or just record the screen you're looking at, as long as you don't have very shaky hands, whatever...
