we are aware of this issue (and have been chasing it for around two weeks already, it is most likely affecting all of the Ubuntu Zesty based 4.10 kernels we have released in the PVE 5 Beta so far). unfortunately there is no reliable reproducer so far - we've just seen three separate spurios occurrences on our dev machines.

if you find/have a reliable way to trigger it (preferably without needing hours of load), you would greatly increase the chances of finding the cause and fixing this (both for PVE 5 and Ubuntu 17.04 ;)). if you do, please include information about the system(s) (hardware and "pveversion -v") with which you have been testing. thanks!
