If no one else gets to it before I do, I can run this command in a day or so; have to reboot in 16.04 side. I get this error as well, but it doesn't prevent the system from booting in my PM 3,1 . . . but, these cert errors continue to show up in the brief TTY window before the log in window shows up. Happy to run apport-collect when I get a chance.

This has been the case since the 4.3.x kernel series and is now with current 4.4.x kernel. At the time the 4.2.x kernel was used **booting the iso went fine!** During the boot-process I get following error messages: "Problem Loading in-kernel X.509 Certificate (-74)" [...] mount: mounting /dev/sda10 on /cdrom failed: no such device stdin: not a typewriter mount: mounting /dev/sda9 on /cdrom failed: no such device mount: mounting /dev/sr0 on /cdrom failed: no such device [...] (initramfs) unable to find a medium containing a live file system The stdin: and mount: lines get repeated several 10 time. At last the boot process stops wuth the (initramfs) line, dropping me in a busybox shell.
