Hmm. There are discussions on Reddit right now indicating the bug still 
occurs even with the latest ESXi6.5u1 (Build 5969303).

https://www.reddit.com/r/homelab/comments/6s5dh6/debian_9_on_esxi_65u1_complete_lockup/

One of the latest comments on the Kernel Bugzilla shows the same:

https://bugzilla.kernel.org/show_bug.cgi?id=191201#c54

(For me, this is really frustrating right now, since I waited until 
ESX6.5u1 before updating my infrastructure and now it seems I have to push 
this update even farther into the future because of this critical blocker 
bug.)

I really wonder what could be done on the Kernel side to avoid the 
problem, since only newer Kernel are affected while older one don't show 
the problem.

Grüße,
Sven.
