Ok, so xfsdump i seeing a short bulkstat, then an EINVAL returned
from the next bulkstat. That's not a race condition, and makes me
think you have some kind of on-disk corruption. The inode it is
starting at when it returns EINVAL is 80508397. Can you firstly
post the output of:

# xfs_db -c "inode 80508397" -c p <dev>

And can you also run 'xfs_repair -n <dev>' on the filesystem and
post the output as well so we can see what state the filesytem is
in?

Cheers,

Dave.
