Load new kernel

Question

I am running arch on Thinkpad x230t and I found this guide with recommendations for running arch on this particular laptop:
https://wiki.archlinux.org/index.php/Le … nkPad_X230
I am trying to install the linux-ck kernel and am having some trouble. I downloaded the tarball and ran the PKGBUILD and ran for a while and finished without doinging anything alarming.
I made the recomended changes to:
/etc/mkinitcpio.conf
/etc/modprobe.d/modprobe.conf
And then tried to run:
mkinitcpio -p linux && mkinitcpio -p linux-ck
It created the first linux image without any problems but failed on the linux-ck, here is the full post:
mkinitcpio -p linux && mkinitcpio -p linux-ck

(Also, what do the 3 warning lines, on the linux image mean?)
What's going on here? Thanks for any help.

Answer 1

What is the output of
# pacman -Qm
From the error that you posted, it clearly states that it can't find the specified linux-ck kernel, which if you installed should be hanging out inside of your /boot directory.
You  might as well post the output of
ls /boot/
As for installing/compiling the linux-ck kernel, the Linux-ck ArchWiki, gives you a general idea, however its the same as installing any custom package (for me at least).  Below are the steps that I personally do, keep in mind that there might be other/easier ways. 
1. Download the latest linux-ck tarball from the AUR, and if you are using an nvidia card you can also grab the proper nvidia-ck package. 
2. Extract the tarball, and cd into the newly created folder
3. edit the PKGBUILD, the only things I change in this file, are the variables in the code below that are set equal to y (enabling the option)
### PATCH AND BUILD OPTIONS
# Set these variables to ANYTHING that is not null (y or hello or 2 or "I like icecream") to enable them
_pstates_pat=y # Enable Haswell support for the new Intel pstate drive
_makenconfig= # Tweak kernel options prior to a build via nconfig
_localmodcfg=y # Compile ONLY probed modules
_use_current= # Use the current kernel's .config file
_BFQ_enable_=y # Enable BFQ as the default I/O scheduler
_NUMAdisable=y # Disable NUMA in kernel config
I personally have just started messing around with the kernel configuration so I'm using localmodconfig as a starting point.  You can however load your own config, or start one from scratch.
4.Save & quit the file, then I personally run the command below, which compiles the package and if successful it installs it.  Keep in mind I'm pretty sure you have to have 'Sudo' set up on the system.
makepkg -ci
If you don't have 'Sudo' or whatever, you can still just run
$ makepkg
# pacman -U pkgname-pkgver.pkg.tar.xz
5. If all is well, I update my grub2
# grub-mkconfig -o /boot/grub/grub.cfg
At this point, you should be able to boot into your new kernel.  Hopefully you use nvidia, and will notice that you have no X working.  You can follow the same outline to compile and install the proper nvidia-ck driver package.
Hope this helps.
