Hi! > Apologies but i do not know how to reinstall the 3.14 kernel, linux is 3.15 and linux-lts is 3.10.. > Can i get from some repo the 3.14 package? If you haven't cleaned your pacman cache (i.e. using pacman -Sc), you'll find a backup of all your old packages at /var/cache/pacman/pkg/. Locate the Linux package you need and use pacman -U <package filename> to install. Cheers!
