Public bug reported: Running 16.04 server without X unter latest Oracle Virtual Box 5.0.12 on Windows. 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. ** Affects: linux (Ubuntu) Importance: Undecided Status: Incomplete ** Attachment added: "apport.linux-image-4.3.0-5-generic.8omxt4_7.apport" https://bugs.launchpad.net/bugs/1531455/+attachment/4544867/+files/apport.linux-image-4.3.0-5-generic.8omxt4_7.apport -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1531455 Title: reboot under Oracle Virtual Box not possible Status in linux package in Ubuntu: Incomplete Bug description: Running 16.04 server without X unter latest Oracle Virtual Box 5.0.12 on Windows.
