Both the archlinux bug and the pull request very much appear to be
unrelated to your issue. In your case, the MMC subsystem is not involved
since the PCI device of the SD controller is not exposed to the MMC
subsystem anymore, just like it is not exposed in lspci anymore.
I suggest as next steps:
- Test whether the issue still exists in the newest kernel that you are
able to install. (v3.17-rc4 is current, v3.16.2 is the lastest on in
the 3.16 branch.)
- Post the dmesg output from a successful boot with 3.15 and from an
unsuccessful boot with 3.16.
