*********** MASS BUG UPDATE **************

We apologize for the inconvenience.  There is a large number of bugs to go through and several of them have gone stale.  Due to this, we are doing a mass bug update across all of the Fedora 19 kernel bugs.

Fedora 19 has now been rebased to 3.11.1-200.fc19.  Please test this kernel update and let us know if you issue has been resolved or if it is still present with the newer kernel.

If you experience different issues, please open a new bug report for those.
Comment 3 Josef Bacik 2013-09-23 20:27:44 UTC 
This is extent tree corruption.  Please make sure you have the btrfs-progs from git.kernel.org and run btrfsck on your device.  If it complains try running btrfsck --repair on your device and see if it fixes the corruption.  If not please file a bugzilla at bugzilla.kernel.org and set the component to btrfs.
