"Here are the symptoms.  I have 2 OpenAFS  Linux 2.4 machines, one SMP and
one not.
--With both of them I access a series of directories and files within
(/afs/w/x/y/z/).
--I then move to the root directory.
--From a third machine, I remove the directories x, y, and z. Then re-add
them (same names) with some other files.
--From the SMP box, I do an ls in /afs/w and see x.  But x is inaccessible.
--From the UP box I can see and access x.
