you snipped the interesting bit there - a couple of lines up
from "naming" ("data   =   bsize=????").

i'm not sure where its going wrong - test 004 does a mkfs, mount,
a series of writes, umount, mount, and then runs xfs_db - could
be anywhere in that chain of events that the blksize goes loopy.
(could try running
        "xfs_db -r -c sb -c p $SCRATCH_DEV | grep blocksize"
at each point to see where it goes wrong?)

cheers.
