Curernt version of btrfs-tools in ubuntu 0.19+20100601 seems old and synchronized with the latest available from Chris Masson on git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-progs.git
Doing so might fix btrfsck reporting errors when dealing with a btrfs partition using compress=lzo.

couldn't open because of unsupported option features (8).
btrfsck: disk-io.c:679: open_ctree_fd: Assertion `!(1)' failed

This is on Precise amd64 but also true of other versions
