I'm sorry for not writing down the trace. I thought it was related to 
vnode's for the DDB trace showed it was tring to get a clean vnode by 
disposing one of FFS's. Since it was during a big copy action buf's might 
have been invalidated in the process. But i think its a vnode problem. I'll 
try to recreate it.
