You could force to install it and then try to boot it with the forcepae
option. as you do for the current kernel.

Check if the kernel package of the kernel you run is in the package cache,
by running

ls /var/cache/apt/archives/*$(uname -r)*

Execute a dry-run of a forced install by running

sudo apt-get --force-yes --dry-run install linux-image-3.19.0-25-generic

Assumed the package is in the cache and the dry run was ok, backup the
the package by running

cp -i /var/cache/apt/archives/*$(uname -r)* ~/Desktop

Ensure that you have a bootable live media, so if something should go wrong,
we can chroot or systemd-nspawn to fix it. Also ensure that you can connect
to the Internet by the live media, to send a request to the mailing list.
After that run

sudo apt-get --force-yes install linux-image-3.19.0-25-generic

Shutdown and boot with the forcepae option.

Assumed you can't boot the new kernel, the GRUB menu likely offers an
option to boot the old kernel, if not you need to fix it by e.g. a chroot
and running

sudo dpkg -i ~/Desktop/linux*deb

Read the Ubuntu Wiki or any howto from the Internet to chroot or
systemd-nspawn your install from a live media.
