If /proc/mounts shows nvsvers=4 I would assume as well that nfsv4 is used. Formally I had the feeling that the examples looked like for really using nfsv4 one would need to have one entry in /etc/exports declaring a fsid=0 (iow the root) and then clients would ask for paths relative to that root.

Deeper inspection of the logs looks like the problem is some connection attempt when xprt is not connected. Part of that procedure is to re-use the connection which forces the xprt to disconnect (so the socket can be re-used). This triggers a state change (TCP_CLOSE) and wakes up the task waiting

It turns out we (you) were not the first ones running into it. The IBM mainframe guys (obviously) have the same need to potentially allow many CPUs. The upstream discussion is here: https://lkml.org/lkml/2014/5/21/251 So, while the change I made does work in this case, it can cause issues.

Pragmatically I would just go for a 14.04 (LTS) install. It is pretty stable already and following updates you would end up with a long-term supported install. If it has to be 13.10 then its either a netinstall with a preseed (so no interaction is required), but that is slightly complicated. Or

Blacklisting simple-framebuffer for the Ubuntu kernel will have no effect because it is built-in. But I am interested in the two dmesg's without any blacklisting to compare the output. Somehow those labelled as own kernel seem to be from a boot with the normal Ubuntu kernel, too. Just the wrong
