The installation of the Arch Linux LTS kernel will not take too long, as it is a small package with only a few dependencies. It is a two step process: Install the Linux kernel of your choice; Tweak the grub config file to add the newly installed kernel; Don’t worry, I am going to show you the steps in details. – rfmodulator Nov 9 at 16:03 To find additional drivers see The rEFInd Boot Manager: Using EFI Drivers: Finding Additional EFI Drivers.

This allows the same kernel image to be used on existing * systems (with a traditional BIOS) as well as on EFI systems. There are various alternative Linux kernels available for Arch Linux in addition to the latest stable kernel. If pacman tells you, that it can't remove a package, that is incompatible with the old kernel, you will have to remove it manually (pacman -Rd conflicting-package.pkg.tar.gz), before installing the old kernel. I think it would make sense to put WAIT or suchlike in the final loop so that such a halted system does not suck power unnecessarily. I ran pacman -Syyu and walked away and let it do its thing.

This is about the initramfs and size to extract, so the initial kernel image loaded to mount your / partition (and decrypt, run file system checks, etc) and then take it from there.
