Interesting, I am on a Precision 7530 on the 1.6.0 BIOS and I am
definitely still having the problems.
Tuomas, what method did you use to update the BIOS and the TB18DC

So, I am seeing this as well on Ubuntu 18.04, with a Dell Precision 7530
with the TB18DC, powered via the dock.

Alright, I have a little more detail, but it's still largely a puzzle.
My current machine state (expected to remain this way until the next
