Directory listing truncated on CIFS mount with kernel error CIFS VFS: Send error in FindClose = -9

[Seth76]

Binary package hint: smbclient

Mounting a network share using CIFS and receiving kernel error "CIFS VFS: Send error in FindClose = -9" after listing directories with a listing greater than 690 characters for the file and/or folder names. The directory listing is truncated at around 690 characters.

SMB share is hosted on Windows 7.

I have tested this issue on the following:
Ubuntu 10.04 with kernel 2.6.32-31 (generic)
Ubuntu 10.10 with kernel 2.6.35-28 (generic)
Ubuntu 11.04 with kernel 2.6.38-8 (generic)

Adding tcpdump output which should be where the issue is occurring.
