I have since upgraded from precise to trusty and made several other
tweaks to improve btrfs performance, so I can no longer provide any
additional log files for the system as it was when btrfs blocked for
several minutes.

Title:
  btrfs blocked several minutes in btrfs-transacti

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  When I first boot up and log into the system, unity takes several minutes to load after I enter my username and password (showing just my wallpaper image).  When I look at /var/log/kern.log , I see multiple occurrences of the message,
  "INFO: task btrfs-transacti:379 blocked for more than 120 seconds" with a stack trace. (see attached /var/log/kern.lorg)

  It may or may not be relevant that my home directory is on ecryptfs,
  my swap is 16GB and encrypted (but doesn't seem to be being used
  during boot up).
