Unofficial user repositories/Repo-ck
Repo-ck is an unofficial Arch Linux repository hosting generic and CPU-optimized kernels and support packages, featuring MuQSS (pronounced mux) and rest of the ck patchset by Con Kolivas. It has been in operation since 2011 and is maintained by graysky.
The official Arch Linux kernel provides a generic package which is built for the x86_64 architecture that will run on any compatible x86_64 CPU. Repo-ck also hosts a generic version of linux-ck but also provides optimized packages for specific CPUs.

Selecting the correct CPU optimized package
When unsure, install the ck-generic group, which works with any compatible CPU. Those wanting CPU-specific optimized packages can run the following command (assuming thatis installed):
$ gcc -c -Q -march=native --help=target | grep march
-march is what GCC would use natively. Refer to the table below for a mapping of this value to the correct group.
|ck-p4||pentium4, prescott, nocona|
|AMD||ck-kx||athlon, athlon-4, athlon-tbird, athlon-mp, athlon-xp, k8-sse3|

Repo statistics are available (package and CPU popularity, number of downloads, and so forth).
There are two mirrors available now:
Please use the BBS thread.
Downloads interrupt regularly
Graysky is using Go Daddy as his web host. Some of the transfers from their poorly implemented server end in an incomplete transfer. To combat this, list the repository address multiple times and pacman will automatically try the next available server. As repo-ck has only one address (no mirrors), use the same server line:
[repo-ck] Server = http://repo-ck.com/$arch Server = http://repo-ck.com/$arch Server = http://repo-ck.com/$arch Server = http://repo-ck.com/$arch Server = http://repo-ck.com/$arch
See this forum post for an explanation of these issues.
