For me, with Btrfs not compiled in the kernel, and with an initramfs, on SSD I get Btrfs loaded at 2.4 seconds. On HDD, it still happens by 6-7 seconds.
So without an initrd and with btrfs compiled into the kernel I'd expect to see Btrfs loaded before 12.4 seconds. Is this an SSD? Or HDD, or hardware raid?
I'd like to see the dmesg from the beginning, until "Btrfs Loaded", for both 3.13.11 and 3.14.1 (via serial console output). I think the clue is in the part before Btrfs loaded.
Also can you post a diff of the config file for the working 3.13.11 and not working 3.14.1 kernels?
