Comment 3 for bug 1485708

It drops to a shell prompt with a motd that says "Emergency Mode please run <some command> to review the boot logs or else run <some other command> to boot normally". I don't recall the exact text but it's a root shell... In 14.04 it did display the "Press S to skip waiting for filesystem". In 14.10 I went to the grub menu and switched to an older kernel and it worked with the skip message, but the newer kernel just dropped to the shell. In 15.04 the newest kernel dropped to the shell and the older kernel just hung indefinitely.

I removes the fstab entry and the newest kernel boots just fine. That's all I know...
