I regularly execute criu tests on linux-next. For this, I use virtual
machine from the digitalocean clould. The current version of
linux-next hangs after a few seconds. I use git bisect to find the
commit where the problem is appeaed. And it looks like the problem is
in this patch.

When the kernel hangs, it doesn't report anything on the screen and
there is nothing suspicious in logs after reboot.

I will try to reproduce the problem in my local enviroment to get more
information.

There is my config file:

Thanks,
Andrew
