I've posted the dmesg output with cifsFYI set to 7, for the failed cvs
update command here:

http://paste.org/pastebin/view/21123

One strange thing I noticed, is that at one point it seems to be doing
something with /home/jbramley/cvs_src/appserv/lib/ix86, but that
folder is not in any of my env vars (PATH, LD_LIBRARY_PATH etc.) so I
can see no reason for it to be looking there. Could this be some kind
of inode confusion on the cifs share?

Thanks,

Jon
