Unfortunately I no longer have the WD15 dock. I switched to TB16 and it

Yea, I think it's related to gnome-shell.
Piotr, can you enable persistent journal for journald?

There was a problem I found a little while back with hooking up dock to

anything else either (both wd15 and tb16 with XPS 9350)

After a week of testing v4.14-rc2, the conclusions remain the same:
- System doesn't freeze when booting up and logging in with the dock attached.
- Ethernet doesn't connect automatically on boot / after login, manual
intervention required.
- System doesn't wake from suspend if the dock was discon
No, after disabling apparmor for dhclient, I'm successfully running v4.14-rc2.
However, it looks like exactly the same problems exist with this kernel as with
v4.14-rc2:
1. NetworkManager fails to connect automatically at startup, but
connects fine after manual intervention.
2. System fails to r
That's probably some AppArmor regression introduced in v4.14-rc2.
Do you still see "Severely broken stuffs" on v4.14-rc2?

There are some fixes about iommu, thunderbolt, ACPI, etc.
If v4.14-rc1 doesn't work, we may need someone from Intel to check it.

Unfortunately that turned out to be a fluke. I had two freezes on
