I've started a separate E-mail about this, but I'd determined those 
crashes were due to d6d458d42e1 ("Handle DisplayPort tunnel activation 
asynchronously").

Since reverting 9d573d1954 and d6d458d42e1 I've been testing several 
resume scenarios (NVMe connected/disconnected and/or external 
DP-tunneled monitor connected/disconnected and have yet to have a resume 
or hibernate failure over several cycles.

Now, how do I help you guys go about fixing these commits?
