I was running v4.14-rc1 for the whole last week.
It is... different.

Good stuff:
- Not a single freeze on fresh boot with dock attached.
- When it connects to eth0, it is stable. Not a single disconnect from ethernet, but that may be as well the result of recent BIOS upgrade to 1.5.0 and dock firmware update that I did at about the time I upgraded to v4.14-rc1.
- Suspend / resume stable, as long as I don't connect/disconnect the dock in the meantime.

Slightly broken stuff:
- Ethernet connection does not come up automatically after boot / login. Syslog shows the eth0 device exists, NetworkManager attempts to connect, it even gets the IP from DHCP, then it suddenly disconnects. I have to manually click in the NetworkManager icon to connect after logging into desktop and suprisingly it connects fine.

Severely broken stuff:
1. Suspend with the dock attached -> ok.
2. Disconnect dock.
3. Try resume -> blank screen, kernel freeze.

Today I also tried 4.14.rc2, but it looks like it is totally uselesss: network connectivity didn't work AT ALL, not even Wifi, and replugging the dock did not help.
