I created a KMP for NFS modules with the patch revert in OBS home:tiwai:bnc942178 repo. The KMPs are being built now, so grab the KMP corresponding to your running kernel, install it and retest. After installing the KMP, check whether the updated nfs is used, e.g. by checking "modinfo nfs | grep filename". It should show the update path, /lib/modules/3.16..../updates/.... If this works, the culprit is the patch. If not, it's somewhere else. -- You are receiving this mail because: You are on the CC list for the bug.

After installing and restarting the system the locking worked again. -- You are receiving this mail because: You are on the CC list for the bug.

This is really strange. That patch really fixes a bug and should have no negative consequences. The fact that does strongly suggests that there is a bug else where that has been hiding. It is possible to get a tcpdump trace showing the problem? i.e on one client run tcpdump -w /tmp/tcp.trace -iany -s 0 port 2049 & then run the java program on both this and the other client in a way that demonstrates the problem. Then kill the tcpdump, and compress and attach /tmp/tcp.trace ?? I might try to have a look next week to see what is happening. -- You are receiving this mail because: You are on the CC list for the bug.

I have submitted that fix for the 13.2 kernel. I don't know how to make a kmp, I think a new kernel will appear in http://download.opensuse.org/repositories/Kernel:/openSUSE-13.2/standard/x86... in a couple of day. -- You are receiving this mail because: You are on the CC list for the bug.
