[Samba] cifs works, but ...

[Goik]

I checked out the most recent cvs version for fs/cifs and was able to 
mount a remote share via mount.cifs. As far as I remember the README 
states that samba 2.2.5 is sufficient. Actually our samba 2.2.5 server 
does not work, but 2.2.7 does.

Unfortunately the whole thing appears to be quite unstable. Shutting 
down the client host with a mounted cifs file system yields several 
kernel faults. Starting a graphical session (gnome) yields lots of error 
messages to the login shell and the beast will not start correctly. 
Maybe this is due to the fact that I'm using quite a new redhat release 
(9.0).

So my question is: Is cifs unstable or do my problems  stem from(e.g.)  
redhat's patched kernel?
