Title:
  [trusty] btrfs causes reboot when running xfs btrfs tests 032 and 033
  back to back

Status in linux package in Ubuntu:
  Invalid
Status in linux source package in Trusty:
  Fix Committed

Bug description:
  Running xfs btrfs specific tests 032 and 033 back-to-back with various
  mount options with 7 target btrfs devices causes the kernel to reboot
  when running inside a virtual machine.

  I've bisected this down and the upstream commit
  2c21b4d733d6e50514e30ffd87110364ddda695b  "Btrfs: fix transaction
  abortion when remounting btrfs from RW to RO"  fixes this, allowing me
  to run the tests through to completion multiple times. Without this
  fix, the tests always reboot on the first iteration using the
  autodefrag mount option.
