Public bug reported:
I have Lenovo ThinkPad e590, which connected via USB Type-C to Lenovo Dock
station.
To doc station connected network cable, USB mouse, keyboard, power, and two
monitors.
On previous kernel versions (include 5.0.0-37) it works ok.
But after update to any version on 5.3.0 I can't use it with doc station:
1) If I boot with connected Dock station then 2 external monitors are black and
laptop monitor the same black
2) If I boot without connected Dock station then Laptop works ok. At the moment
when I connect USB Type-C cable to laptop screen become black, and 2 external
monitors show the image, but it hangs:
I can move the mouse cursor but all other UI hangs, even the clock does not
work, only REISUB helps.
