Unfortunately this does not seem to fix the problem (similar hangs repeatedly occur on patched 11.3 systems). I notice that a flood of Fedora bug fixes has been made by the NFS committers, especially Trond Myklebust. The long and winding road starts at their bug 672305: https://bugzilla.redhat.com/show_bug.cgi?id=672305 There are several fixes mentioned here, but this also chains to their 692315. If the OpenSuse NFS person could please take a look at this and see if it's been committed yet and if not, please consider doing so. I'm not sure if this should be critical. It doesn't occur that often, but when it does, there's evidence that it can lock up the connected file server too.
