Hello List,

while running Kernel 4.4.2 on the host and Kernel 4.1.18 in guests we're
seeing frequent hangs inside our guests.

This happens for all guests at the same time.

All of them show a trace + soft lockup while seeing no message at the host.

Is this a known bug? I expect this one inside the kernel kvm module as
it happens at the same minute on all guests.
