*ERROR* [CONNECTOR:71:eDP-1] Link Training failed at link rate = 540000, lane count = 4

Hi,

When booting my Asus Zenbook UX31A-R4003X with an external monitor connected using micro HDMI, I get the following errors and the PC is somewhat stuck. Plugging the monitor after booting does work.

I'm using Fedora 28 running Linux 4.17.14-202.fc28.x86_64. Please ask if you need more informations and please tell me if my problem is not related to this bug and I need to open a new bug report.

Regards

This bug needs to be split. I already moved the icl-dsi failures to https://bugs.freedesktop.org/show_bug.cgi?id=110689, but we need to move the icl-u2 issues to another bug, then make CFL's '*ERROR* Link Training Unsuccessful' either as a separate bug or move it to a bug with all the platforms affected by this.

For icl-u2 separate bug is created Bug 110690. CFL's '*ERROR* Link Training
Unsuccessful' reported Bug 110691.
