*nod* - how are you creating these fuzzed images, i.e. what mkfs
do you start with.  Are you randomizing mkfs options, and it just happens
that the ones with problems are the v4 filesystems w/o crcs?  That would
certainly make sense.

Or are you manually restricting the type of filesystems you create for
fuzzing?
