FWIW, I've been updating every few days, running two different snapshots 
between 3.16-rc4 and rc5, and now rc5 itself, and haven't noticed this 
issue.  Dual SSDs btrfs raid1, but partitioned up so the biggest 
partition is under 50 GB.

I've been doing some very heavy (gentoo) package building and shuffling 
around the last few days trying out the kde-frameworks/workspaces-5 
stuff, then deciding it's not yet ready for me, too, so I've been working 
it a bit, too.

But certainly YMMV, and I did have some nasty trouble a few weeks ago, 
which triggered a btrfs restore and then a mkfs on a couple of the 
filesystems.  But nothing at all strange with btrfs since then, or 
really, for awhile before that either.
