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.
