I have several mounted CIFS shares to a Win XP Pro server. This
usually functions well for a few days/hours then I get input/output
errors. When I unmount them and try to reconnect I get:

# mount -a -t cifs
mount error 5 = Input/output error
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)
mount error 5 = Input/output error
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)


I get this in my syslog

Aug 7 11:39:38 debian kernel: CIFS VFS: Send error in SessSetup = -5
Aug 7 11:39:38 debian kernel: CIFS VFS: cifs_mount failed w/return code = -5
Aug 7 11:39:38 debian kernel: CIFS VFS: Send error in SessSetup = -5
Aug 7 11:39:39 debian kernel: CIFS VFS: cifs_mount failed w/return code = -5

I hope somebody can help with this - its a very frustrating problem.
I haven't found a fix anywhere on the net.

This is a stab in the dark: Did you already try to explicitly disable
the Linux extensions? Run

echo "0" > /proc/fs/cifs/LinuxExtensionsEnabled

before you mount the share.
