From: Dave Chinner <dchinner@redhat.com>

This has found several issues with recovery on CRC based
filesystems. It is based on a test case for a dir3 assert failure
provided by Michael L Semon.

The test seems to pass now fine with or without CRCs enabled with
all the kernel patches I've posted over the past day.
