libsmbclient: System freezes when changing directory to Samba mounted share on NetApp server

[vogu]

Package: libsmbclient
Version: 2:3.2.3-1ubuntu3.3
Severity: important


I have a server from Network Appliances that I mount on my Xubuntu 8.10 via
SAMBA or CIFS. 
Mounting a share from that server is ok, but when changing to a directory 
below that mountpoint, the system most often crashes.     

The directory in which one I change has some 250 directory entries. In the  
few cases, where the system doesn't crash and where I can do an ls, the
result only shows some 145 of the 250 directories.

As I told, the system normally freezes. It does this nearly everytime when
entering cd followed           
by TAB (for bash completion). In that case, nothing works any longer, not   
the mouse nor the keyboard. The system can even not be pinged any longer.

I do not use any special mount options, just 
   mount.cifs //server/share /mnt/xxx
or
   mount.smbfs ...

I can easily reproduce the problem on
 - Ubuntu 8.10 
 - Xubuntu 8.10
 - Debian Lenny (since I updated it 2 weeks ago; before that update, there
 was no
 problem)

The problem does not appear on
 - Ubuntu 8.04
 - Debian Etch
 - on any Ubuntu or Debian system, when mounting a Samba share on a Linux
 server; only when mounting a NetApp share the problem appears.

I am not sure if libsmbclient really is the package having a problem, but
everything points into that direction. It also could be the kernel or ...    
             
I made my tests on 4 different PCs with the same results everywhere.

I saw a similar bug report on launchpad.net/ubuntu, it has the number
296304.
