I upgraded my kernel so my version is now:

The problem has not been solved and I still get the previous errors.

Ok,

Step one is to grab the development version of btrfs-progs, which
currently sits in the dangerdonteveruse branch:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-progs.git dan=
gerdonteveruse

Run btrfs-debug-tree -R /dev/sdh

and then run btrfs-debug-tree -b 5568194695168 /dev/sdh

and then run btrfsck /dev/sdh

Send the results of all three here, it should tell us which tree that
block belongs to, and from there we'll figure out the best way to fix
it.
