That would be great, thanks.  And could you collect the contents of
/proc/net/rpc/{nfsd.fh,nfsd.export}/content at the same time?  (I think
you already sent some; but I'd be curious to match them up with the
packet trace.)  Also, the output of "blkid" might help diagnose any
problems with uuid's.

(Also, I think it's probably a totally different problem, but I found a
problem yesterday with out-of-date uuid information that appears to be
due to selinux preventing rpc.mountd from opening block devices; are you
using selinux, and if so does turning it off (setenforce 0) help?)
