Lenovo USB-C Hybrid Dock
 

Greetings,

i have the following major situation:

On around 20 Lenovo X380 and ~ 10 Yoga 370 using both the USB-C Hybrid and Standard Dock the attached Displays (Connected via DP - DP and / or HDMI - DP) go black for a few seconds and then back to normal.

I have been sent a beta firmware from Lenovo, but this did not resolve the issue, and i have had no response since then. Sofar from what i can see, the USB-C Drivers are crashing. Would appreciate if there is a fix for this issue.

Second error that can occure, but not is often: Notebook is slow as hell. Only unplugging the Dockingstation from the Notebook and disconnecting the PSU will resolve this. Most likely also due to USB-C and/or the graphics card crashing. But i have no fresh log from this.
