I see the same behaviour, but I'm not sure if the cause is the same, on 4.4.0-112-generic and 4.4.0-116-generic. In my case, the VM remains responsive for a variable amount of time. Sometimes it works long enough to login via SSH, at other times it does not get to the login screen. In almost all circumstances I cannot see what is wrong with the system (nothing gets printed to screen), and I see the VM use up all available CPUs. Likewise, the only way to get out of that is to do a hard reset.
Booting with 4.4.0-109 never gives this problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1751294 Title: Kernel linux-image-4.4.0-112-generic prevent the boot on Microsoft Hyper-v 2016 Gen2 VM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-meta-lts-xenial/+bug/1751294/+subscriptions -- ubuntu-bugs mailing list firstname.lastname@example.org https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
