During quick tests I saw similar problems with the Fedora rawhide
configuration in 4.10-rc{1,2} (haven't tried rc3/mainline yet). My free
time was extremely limited in the past few weeks as I was traveling
(often without the machine), hence I couldn't look closer into it yet
(sorry, I nevertheless should have reported it).

Same here.

Did you try to check if the machine is still reachable via ssh (it looks
like it might) and if there is anything helpful in dmesg? That's on my
todo list.
