Public bug reported: I encountered an kernel trace regarding Cachefilesd running 3.11.0-7-generic #13-Ubuntu SMP Tue Sep 10 20:55:38 UTC 2013 x86_64 GNU/Linux under Debian Squeeze 6.0.7 amd64 on an Opteron barebone.
This server is an NFS client using cachefilesd. The NFS server is Debian Squeeze 6.0.7 amd64 running 3.2.0-0.bpo.4-amd64 #1 SMP Debian 3.2.46-1~bpo60+1 x86_64 GNU/Linux and nfs-kernel-server on an Opteron barebone as well. No kerberos is in use. The system is basically the same as in Bug #1225494 . However, named bug is regarding a problem with nfs_idmap whereas this seems to be a problem with fscache. The trace is attached.
