I had the same problem some clients worked some didn't. Finally I tried disabling NBD and enabling NFS as described here: http://doc.ubuntu.com/edubuntu/edubuntu/handbook/C/customizing-thin-client.html http://doc.ubuntu.com/edubuntu/edubuntu/handbook/C/customizing-thin-client.html . I followed the instructions under "However, some people still want to use NFS. Fortunately, it's easy to switch back to NFS, if it's so desired:".
Now my Dell OptiPlex GX1 client comes up, finally. I realize this is just a workaround, there's something wrong in the NBD setup but I couldn't figure it out. I'm using Ubuntu intrepid 8.10.
