Oh dear.  That warning is not necessarily telling us that there's a serious
problem - often it's fairly harmless.  Did the filesytem misbehave in any
other manner?

A problem we have here is that nobody really maintains smbfs any more, and
it has problems.  I was hoping that the stock answer to that would be "use
cifs", but for some reason that doesn't seem to be happening.  Have you
tried it?  (Last time I looked, cifs didn't work against win98 servers -
maybe that got fixed).
