The cifsFYI output shows this toward the end:

Oct 14 19:22:14 ttimozilla kernel:  fs/cifs/connect.c: invalid transact2 word count
Oct 14 19:22:14 ttimozilla kernel:  fs/cifs/netmisc.c: Mapping smb error code 2 to POSIX err -2
Oct 14 19:22:14 ttimozilla kernel:  fs/cifs/cifssmb.c: SetPathInfo (file size) returned -2
Oct 14 19:22:14 ttimozilla kernel:  fs/cifs/inode.c: SetEOF by path (setattrs) rc = -2

SMB error 2 looks like:

#define ERRbadfile              2       /* File not found. The last component
                                           of a file's pathname could not be
                                           found. */

...any chance you could send me a binary network capture of this failure?
