Oh, sorry, actually it was just me hitting too many Fs. So 32767 (0x7fff) should be enough. I guess the other value is ok, too just sets too many bits in the mask. Yes, the messages should end up in syslog. With all debugging turned on there will be quite a bit of logging going on. Hope this does

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.

Now this also explains why I had a hard time (iow was not being able to) reproducing this here. Since this indeed is a rather unusual corner case, I can put it a little lower on the list. Still I would try to understand the debug output enough to have some better idea about how that windows app is

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.

It might be a bit unclear but the main task is fix released because Utopic (14.10 and current trunk) is based on 3.15 right now (will move to 3.16 before release). So Utopic is ok. For Trusty this is still in the mill. The patches have references to this report. So you should see an automatic

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

Hi Salvatore, so that old crash really looks quite similar. One interesting difference is that this process did simply exit and was not killed. Which sounds, like you did suspect as well, that this is not a regression in a recent kernel but something in the way things are executed changed and
