         ... how on earth can interface aliases cause it to croak in namei?
 
 I don't know - I merely observe & report the problem behavior, and the only
 change to system configuration that I presume caused it.
 
 It is important to note that the NFS server was routing IP packets between
 two interfaces, in addition to serving up NFS - the interface alias addresses
 were those of my house router on two physically separate networks which the
 NFS server also had its own interfaces and addresses on; This is not merely
 a matter of an NFS server with one or more additional interface aliases.
 
 Further, now that I have a dedicated router deployed once again and the
 interface alias addresses have been removed from the NFS server (and its NFS
 services turned back on), it is stable once again. So, I think there is a
 pretty strong circumstantial case linking this particular configuration change
 and the subsequent locking panics.
