[PVE-User] OpenBSD problems (freezing console, lots of time drift) on Proxmox 5.0

[Wolfgang Link]

It looks like a kernel problem.
Not sure what exactly is the problem, but every kernel(mainline and ubuntu) larger 4.10 will trigger this behavior on some HW.
Debugging take some time.
I will report the result in this forum thread.
