What version of nfs-utils are you running? We haven't been using
nfsservctl(3, ...) on 2.6 kernels for ages - which probably explains
why exp_export() has suffered so much bit-rot. When I convinced
exportfs to use that nfsservctl I got a very similar oops.
This patch fixes it for me. Does it fix it for you too?
Thanks,
