Thanks, I installed kernel 3.18.3, and followed your instructions to run btrfs 
check --repair from initramfs.

But now that I have kernel-3.18.3 installed, I tried (fully) booting into it.  
Surprise, it won't boot.  Choosing it from grub, I get the usual boot progress 
indication, but hitting esc to show messages, all I get is a black screen.  
Can't switch vt.  No indication of disk activity.  Nothing found (later) in 
/var/log/messages about 3.18.3 - I don't think the boot got far enough.

Booting up 3.17.8 works fine.
