Everything works quite well, including suspend. But the computer simply rebooted, instead of resuming from suspend. I never use suspend, so It is working fine for my daily needs. I use the kernel full time daily without any major usability issues, save for this small issue that normally wouldn't effect me.
WORKAROUND: Edit the /etc/default/grub file:
gksu gedit /etc/default/grub
Look up the line where it says:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
and change it to:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_sleep=nonvs"
Save and close the gedit file. Update the GRUB menu:
sudo update-grub
Reboot and enjoy!
