The repeated entry: CIFS VFS: Send error in SETFSUnixInfo = -5 is expected on connection to certain older versions of Samba servers (or other servers that only partially support the current CIFS Unix Extensions). It is harmless. It would be useful to know (e.g. if it is possible to trace the network traffic on the server side on your NAS box) whether any network traffic from the client is being sent when (or just before) the hang occurs. It is possible that the restarting of the NAS box allows reconnection of the smb/cifs session to proceed which presumably could be hanging or looping in the network adapter driver, the tcp stack or cifs on the client, but it is hard to tell without more information. I don't know much about either of the GigE drivers loaded on your system to determine if there is an easy way to tell their state. There are various ways to analyze system hangs including (at least in some cases) getting a system dump which can be used to isolate the failing location - hopefully linux-kernel-owner@vger.kernel.org wrote on 01/30/2007 06:37:48 AM: > Hello, > > I report a problem that occurs on a Core2 system (x86_64 used) with a Linux > 2.6.19.2, when i use a NAS : Maxtor Shared Storage II 320Go (Linux 2.6.12 > inside). > > In fact, this NAS can be web-configured to sleep after 30 min.
