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.
