 Maybe that's rump.
 
 msdosfs:
         KASSERT(tcnp->cn_cred == cred);
 
 genfs:  /*
          * XXX Want a better equality test.  `tcnp->cn_cred == cred'
          * hoses p2k because puffs transmits the creds separately and
          * allocates distinct but equivalent structures for them.
          */
         KASSERT(kauth_cred_uidmatch(cred, tcnp->cn_cred));
 
 
 When I replaced the KASSERT in usr/src/sys/fs/msdosfs/msdosfs_rename.c and
 tested it (correctly) this indeed fixed the problem.
