I have tryed other 3 times and checked and rechecked spelling. Nothing does change. I then booted with "modprobe.blacklist=nouveau" and afterwards did "modprobe drm_kms_helper poll=0" and "modprobe nouveau". The problem disappears but also the output on the screen. I can not reproduce it every time and it could be related to when and how i switch between tty. I got this in dmesg (only in this particular case), dont know if it is related.
