Btrfs devel - Apr 2014 - Can anyone boot a system using btrfs root with linux 3.14 or newer?

Can anyone boot a system using btrfs root with linux 3.14 or newer?

Because I can't.

I'm trying to move some 3.13.x based systems to 3.14.x and the kernel panics
during boot. It says to append a correct root=sdaX partition, but the one
provided is correct, because if use 3.13.x with the same kernel command line
- the system boots fine.

The thing is - there is an ext2 /boot partition and root / is btrfs, like
so:

# cat /etc/fstab
#
# /etc/fstab: static file system information
#
# <file system>        <dir>     <type>    <options>    
<dump>
<pass>

#/dev/#REISERFS_ROOT#  /         reiserfs  defaults               0      0
#/dev/#EXT3FS_ROOT#    /         ext3      defaults               0      1
/dev/sda2              /         btrfs     relatime,compress=zlib 0      0
/dev/sda1              /boot     ext4      defaults               0      1
#/dev/#JFS_ROOT#       /         jfs       defaults               1      1

Here is my relevant GRUB config file part:

#menuentry 0
title Linux
    root (hd0,0)
    kernel /vmlinuz rw root=/dev/sda2 vga=6 raid=noautodetect

And for the record - I used the same kernel config as the one from 3.13.x -
I just copied my old .config file over to linux 3.14.x sources and did a
"make olddefconfig" and compiled my kernel, just as I did with all
previous
ones...

Ideas?
