--- Comment #1 from Theodore Tso <tytso@....edu> ---
Are you running this under KVM?   The most recent spate of complaints about
this (which just means that ext4 discovered an inconsistency in the allocation
bitmaps; it doesn't automatically mean it's an ext4 bug) was caused by a bug in
the hypervisor layer of the Host OS.   See the resolution of this bug:
