I don't know what the cause is, but I think I've got the trigger.
Those errors appeared when using rsync on a directory containing a file that was 
written to (extended) while the rsync was running, which seems to be a 
situation, where rsync causes a lot of stress. It certainly takes a hell of a 
lot of time.

I suspect any of the ext4 related commits from Jan 9th/10th. From the log I 
guess they should still exist in 3.3-rc1. I'm currently testing that, but 
unfortunately that might take some time.

And a short repeat: I'm using an md, but no lvm.
