I can't help w.r.t. getting the NKM to work (I've always thought that the
NLM protocol was a crock and avoided using it). But, here's a couple of
things you could try to avoid using the NLM.
- Do the Linux mount with the "nolock" option. (If Ubuntu has a
"locallock" option, that would be even better, but I'm not sure what
options recent Linux's have for nfs mounts.)
- Download my server patches (ftp.cis.uoguelph.ca/pub/nfsv4/FreeBSD7) and
switch to using nfsv4, which has integral locking in the protocol.
Have a good holiday, rick
