Hello. There is the same problem with a new, latest Linux 4.4.0-115-generic kernel (updated today). I've tried to boot system with 'nosplash' option (set via GRUB etc.) and it seems, that there is a problem with:
Gave up waiting for root device. Common problems: - Boot args (cat /proc/cmdline) - Check rootdelay= (did the system wait long enough?) - Check root= (did the system wait for the right device?) - Missing modules (cat /proc/modules; ls /dev) ALERT! UUID=* does not exist. Dropping to a shell! BusyBox v1.22.1 (Ubuntu 1:1.22.0-15ubuntu1) built-in shell (ash) Enter 'help' for a lost of built-in commands. (initramfs) _ However, I've decided try to boot v4.4.0-115-generic kernel once again, because above 'ALERT!' message was very interesting for me, but this time, without 'kaslr' option. So, in a GRUB menu I removed this option and press CTRL + x. Everything was okay - system boot normally. It seems, that there is a problem with a 'kaslr' in latest 16.04 LTS Release kernels (I'm having this problem since update to the v4.4.0-113.136 kernel version. Should I create a new bug report about 'kaslr' and latest kernel versions? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1748710 Title: Linux 4.4.0-113.136 (i386/x86_32): failed to boot and BusyBox v1.22.1 built-in shell (initramfs).
