My earlier message was incorrect; I had misunderstood the problem.
More correctly now:

It seems to me like this error should be caught in step 4, and indeed
it is, but sense the diskfs_looup returns an error, it never fills
tmpnp, so the immediately following assert gets signalled.  It should
be satisfactory to rearrange the code.

First, Richard, can you confirm *which* assert is failing for you?
