TW booting only without "quiet"

English Install/Boot/Login
1

Very strange thing: My notebook won’t boot. I’m on current TW (including all updates, and pacman). After starting the notebook, the grub2 screen appears. I don’t do anything and so the default kernel starts. Booting stops with this error on screen:

[drm:intel_dp_link_training_channel_equalization [i915]] *ERROR* failed to update link training

If I type “e” and delete the booting option “quiet”, the notebook starts, I get all the messages on screen, everything back to regular.

jounalctl --boot=1

ends with these lines:

Any ideas?

Maybe related to this?

Try disabling plymouth by adding “plymouth.enable=0” instead of removing “quiet”.

You might also try an older kernel, as it seems to be a regression there.

Yes, plymouth.enable=0 did the trick as well. So probably the same bug. Thank you!
