are those images created with grub-n-iso persistent USB's? that will create differences in timing etc especially on 2nd and later boots. Atleast on vmware this issue seems to be a race issue in the systemd units.
I don't think syslinux vs grub should make any difference, I see the same issue on an installed system under Vmware. It just doesnt hang there, since there is no prompt asking for user input. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1447038 Title: Shutdown/Restart of live session guest does not work in Virtualbox, and VMWare To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/1447038/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
