elementary OS hangs at boot at 'Restoring resolver state…'

Question

I'm running elementary Freya 64 bit and using the Nvidia binary driver v340.76.

Yesterday some upgrades were installed, including apparently the kernel version 3.16.0-46-generic.

Today I rebooted the system and it hanged on Restoring resolver state…. The only way I could get it to boot was to select the previous kernel (3.16.0-45-generic) from the advanced options.

I've tried the answer given here, basically adding acpi=force to GRUB_CMDLINE_LINUX_DEFAULT :

sudo vi /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash acpi=force”
sudo update-grub

but it didn't work.

Any ideas how to solve this?

Run the following command to uninstall the new (broken) kernel
