Title:
  can't write to a BTRFS disk with my powermac

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Hi,
  When I try to write to my BTRFS formated external disk, I get an error message explaining the file system is mounted read only. Indeed, I can still read data in it.

  A dmesg shows the following errors:
