System goes to emergency mode as /boot/efi could not be mounted

[Prasanna Kumar]

System was booting normally with 16.04. Upgraded to 16.10, system goes to emergency console on every boot. This happened due to timeout in mounting /boot/efi. Commented out /boot/efi entry in /etc/fstab. System boots after that. But wifi, bluetooth and sound does not start automatically now. I have to load iwlwifi module to start wifi, snd_hda_intel to get sound working. I am using a Lenovo G50-80 laptop. Everything was working fine in 16.04.

Booted into Windows 8 once and came back. Now audio and wifi starts automatically. Don't know if it is a coincidence.
