Ubuntu-Server does not launch after kernel update to 4.4.0-116

[Falk Ziegler]

I am running Ubuntu-Server 14.04.5 LTS in a HyperV-VM with the Xenial HWE-Stack enabled. Until the kernel 4.4.0-112 everything ran smoothly, but with the kernel update to 4.4.0-116 the system cannot be launched and stops during the boot with the following error message:

Gave up waiting for root device. Common problems:
 - Boot args (cat /proc/cmdline)
  - Check rootdelay= (did the system wait for the right device?)
  - Check root= (did the system wait for the right device?)
 - Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/disk/by-uuid/99acf869-911c-47ae-917f-7e82d3c99b8e does not exists. Dropping to a shell!

Also same behaviour with the latest kernel 4.4.0-119.

I already tried to boot with the rootdelay=10 argument but this has no effect.
If you need further informations please tell me. Thanks for your support.

Best regards
Falk

If the mainline kernel still exhibits the bug, we can perform a kernel bisect to identify the commit that introduce the regression.
