Title:
  Kernel BUG shortly after mounting btrfs filesystem

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  This bug happens entirely reproducibly after mounting a multi-disc
  btrfs filesystem I have. It is reproducible on the current Vivid 3.18
  kernel and the mainline 3.19-rc5 build; I recall this bug also
  happening on Utopic's 3.16 kernel, but don't have logs.

  All processes that touch the filesystem then hang indefinitely in the
  kernel.
