When I mount linux/windows samba shares with smbmount (command line or with 
komba2) I have this kind of error :

[thomas at Daemon / ]$ cd Dance\ \&\ Techno

Erreur de segmentation

The problem is that the processus (here ls, but the same happened with xmms or 
konqueror) turns itself into the 'D' mode. A kill -9 with root privileges will 
not kill him. umount -a -t smbfs will not work (device busy) even if i try the 
force option. When trying to reboot ('reboot') mount warns that it can't unmount 
the mounted filesystem (device busy) and it hangs. I am forced to use alt+sysRQ.

Has anyone ever had this problem ? Can this be related to the original mount 
program I use ? For the moment I am forced to use smbclient ... damn

I'm on linux 2.4.18 - mandrake 8.2
I had this problem with samba 2.2.3a and i switched recently to 2.2.4 but the 
same problem still occurs (on the same shares !!).
