post the exact specs and precise command run in the PR. We found an old post 
from 2004 when we looked up the process state obtained from CTRL+T -- flswai 
-- which describes the symptoms nearly perfectly.

Sorry, I just now saw this.  :(

Are you still seeing this, and if so can you get a crashdump?  Also, I'm 
curious if you only see this with SUJ or if plain UFS+SU works fine?
