Do you get the same errors? He gets error messages for every file he lists
while Ben's problem showed as a completely silent listing.

Your subject is a bit wrong I think, a NetApp-thingy isn't the same as an
NT, or is it?

That one is new. The problem I was thinking of was a client/server
communications problem (server I think, it stopped in mid listing with an
error). The log output for that looks something like this:

smb_refill_dircache: readdir failed, result=-2
smb_proc_readdir_long: name=, entries=117, rcls=1, err=123

Have you tested < 2.2.14? does it do the same?
Does smbclient work?

Does your problem only show on large directories, Kenneth has problems
with all files/directories as I understood it. Could you compare your
problem in detail with his reports and see if the symptoms really are the

Ben never posted his log messages but he was experiencing this with 2.2.12
and the behaviour looked just like it did for me so I assumed it was the
same problem. That problem is fixed in 2.2.14+, I believe this
NetApp/Toaster (they have someone working there just thinking about silly
names ... :) problem is something different.

Test with a "plain" 2.2.14 kernel (plain = without vendor patches), test
with a "plain" 2.2.13 kernel.

Add a line
to fs/smbfs/Makefile and rebuild & install your kernel + modules. It will
then output a lot more about what it is trying to do. Send that log with
kernel version to me and I'll have a look.

You will probably not get an answer or a fix, but maybe then I'll know
which questions to ask and not just throw everything I can think of at 
you. :)

If you feel like debugging the problem yourself, adding printk's to
fs/smbfs/proc.c:smb_proc_readdir_long to try and understand what is
happening is a start. As I read the code it seems like the only thing that
should be able to cause that message is if what the server returns
  server->rcls == ERRSRV && server->err == ERRerror
ERRSRV = error generated by the server
ERRerror = "Non specific error code"

If things work for short directories but not for long it may be something
in the "findnext", or not.
