I can reproduce it every time when copying large (>2G) files over NFS. The call trace is at https://bugzilla.kernel.org/attachment.cgi?id=26519 Needless to say it results in a system crash (kswapd deadlock, network stack failure because of memory allocation failure for SKBs, etc.). Trond Myklebust closed this bug a while ago, but apparently it's not completely fixed and needs to be re-opened. -- Leszek Urbanski
