As soon as I call the smbclient from A4000 to list the shares on the 1200 harddisk starts to read sometime and then computer crashes with software guru.
Increase stack size. All those Linux ports need huge amounts of stack. Use 50000 or 100000 bytes stack. For all components of Samba (so you also have to use this stack for Genesis which calls smbd and nmbd).
