Kernel EFI stub loader support was added in kernel 3.3, but I'm stuck on 3.2 running an Ubuntu 12.04 64bit distribution. Is there a way for me to somehow bring that stub loader support into my kernel?

  • The easiest solution is to use a 3.3 kernel (probably custom built, I don't know if Ubuntu ships with EFI stub by default). Would that be an option? – Marco Jan 11 '13 at 7:57
  • Yeah, I'm looking into that now. I'm probably going to go straight to kernel 3.7, as I need fixes implemented in kernel 3.6. – Naftuli Kay Jan 11 '13 at 17:32
  • Do you know where I can get Ubuntu's config and Module.symvers files for building a kernel? I want to keep this as simple as possible. – Naftuli Kay Jan 11 '13 at 18:07
  • I don't know about Ubuntu, but on Debian the config is included in the linux-image-XYZ binary package. If you need build instructions, here are the necessary steps to install Debian on an UEFI system. The guide works for Ubuntu as well. – Marco Jan 11 '13 at 18:22
  • It could be located in those packages on Ubuntu, too. – Naftuli Kay Jan 11 '13 at 18:24

I ended up simply installing a later kernel. You'd be surprised how easy this is. Simply searching packages.ubuntu.com for kernel packages allowed me to find the packages I needed. I needed to install essentially linux-image-3.X.*, linux-image-extra-3.X.*, and linux-headers-3.X.*. Posting from a nice, shiny EFI-booting Linux.
