--- Comment #8 from Holger Schurig <holgerschurig at gmail.com> ---
A rebooted and retried (still with debugging), and this time my text didn't
come back. So out of 4 tries, twice I got the text back, twice not.

I never got the text back without drm.debug=14

I increase my kernel's log buffer and try to get a full dmesg log when text
doesn't came back and will attach that as 4.txt.
