I've been using archlinux with a patched kernel on my surface pro 3.
I switched to ubuntu now and want to use the kernel that includes all the patches from arch with ubuntu.
What is the best way to add the Kernel?
Can I simply copy the vmlinuz and initramfs and update-grub?

I copied the files and updated grub, which worked fine.
But when I boot the new Kernel I get a Kernel panic:
Unable to mount root filesystem.enter image description here

The Kernel here was provided precompiled with with /usr and /lib as a .tar.gz archive.
The Kernel package I used does not provide that,it just contains the patches, so I can't justcopy /usr and /lib from the archive.

I could copy them from my arch distribution running this Kernel, but what specific directories would I have to copy, the whole /usr and /lib?

  • In short - yes, in long - yes, but you probably may have a problems with loading modules and other things. Try to just copy these files in boot directory and boot manualy from grub CLI, it's interesting experiment. But I don't think ubuntu have old kernel without patches, try to search kernel ppa for vivid (there is 4.0RC)

  • Thanks I will try it later. Most patches for the surface pro 3 are unfourtunatley not in the mainline kernel yet so you need to add them yourself.

  • I have compiled it myself, but there is one in the AUR.

  • Booting the kernel results in a Kernel panic.

simply copying the vmlinuz and initramfs and update-grub might work, but you might also need lib and usr. There is an interesting post that shows it is possible to use arch kernals in ubuntu.
