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.
