Still nothing useful there. Our kernels have nfs/sunrpc debugging enabled, so let's try enabling that and see what information we can get. I haven't used this before, so there may be a bit of trial and error involved.
Start by running these commands: $ rpcdebug -m rpc -s all $ rpcdebug -m nfs -c all Those very well may require sudo. After that try to mount the nfs shares. I believe the debug output will appear in dmesg, so check there, if not check the journal. Wherever they appear, capture that to a file and attach it to this bug. Let me know if you have questions.
