Have you tried playing with the journal segment size with gfs_mkfs -s ?
Scaling that down along with the journal size might have some effect.
You might also disable quotas if you haven't yet which should reduce the
transaction sizes.  WRT the assertion, that might be something that's
fixable, but it would require delving into the logging code a bit.
