Hi,
We still experience this bug. We use Hyper-V 2012 and use Veeam to
create VM backups (though this fact might be irrelevant). We upgraded
our Ubuntu 14.04 to the latest xenial kernel (4.4.0-91) and still
experience the VM hanging/freezing/stacktracing regularly directly after
backup. Sometimes the server becomes unresponsive and shows the
following error in the syslog: "Hyper-V VSS: VSS: freeze of /boot:
Operation not supported" (after that it dies). The stacktrace included
now did not crash the server, but it was definitely caused by the VM
backup.
Some more info:

I hope this issue can get fixed soon. Stop making backups is not really
an option for us.

Bug description:
Description: Ubuntu 14.04.5 LTS
Release: 14.04
Hi, after installing kernel 4.4.0-67 or later I cannot backup my Ubuntu VM's
on Hyper-V.
Microsoft Hyper-v 2012r2 Gen2 VMs
See Attachment for what happens is immediately after backup starts I
get an error.
Eventually the kernel reports it has run out of memory and the machine
just continuously scrolls errors message related to page allocation.
When reseting the virtual machine no logs can be found of the problem.
