This is an entirely different problem and may have long been fixed;
I count at least 6 patches for tx aborts in my 4.1++ tree alone.
We're talking about patches that I can guarantee you are not running.

If Pivotal needs some help with stable btrfs backport fixes I might be
able to resurrect my old 3.19 patch queue (check my Github!), but this
is close to Zombie Olympics.. :)

cheers
Holger
