After issuing 'shutdown -r now' the following boot process is not successfull and hangs with message ---[ end of Kernel panic - not syncing: VFS: unable to mound root fs on unknown-block(0,0) If using 'shutdown -h now' and then staring the machine anew from Virtual Box manager, then the system starts as it should. Thus, for short, warm reboot hangs and cold reboot operates as desired. I have the feeling that this behavour was introduced with kernel 4.3, but I cannot swear on it. Imho, may also be a bug of Virtual Box. The result of ubuntu-bug linux is attached. --- AlsaDevices: total 0 crw-rw----+ 1 root audio 116, 1 Jan 6 11:34 seq crw-rw----+ 1 root audio 116, 33 Jan 6 11:34 timer AplayDevices: Error: [Errno 2] No such file or directory ApportVersion: 2.19.3-0ubuntu2 Architecture: amd64 ArecordDevices: Error: [Errno 2] No such file or directory AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: DistroRelease: Ubuntu 16.04 HibernationDevice: RESUME=UUID=cbc2edd0-9886-40c6-bf14-d75f638fc4cf InstallationDate: Installed on 2015-12-23 (14 days ago) InstallationMedia: Ubuntu-Server 16.04 LTS "Xenial Xerus" - Alpha amd64 (20151115) IwConfig: enp0s3 no wireless extensions. lo no wireless extensions.
