Unfortunately there's are no other messages above this in 
/var/log/messages. I checked carefully for any asserts.

It's xfs (nobarrier opts) running from a Linux MD software raid device 
(no LVM). It uses raid6 on 11 1TB discs, using a chunk size of 32 kB. 
The filesystem is 88% full. The discs are on a 3ware 9650SE controller.

The array has a set of backup "snapshots" with hard links created using 
the rsync --link-dest feature. We also used --sparse when doing the 
rsyncs. We have snapshots for a set of user directories, one for each day.

The message occured while rsync was writing to the array (creating the 
snapshots) and it was being read by rsync or a tar to tar pipe to a 
second btrfs array.
