Are all the thin clients the same hardware? Do you have a custom lts.conf specified? I've had clients hang due to issues with some modules I was loading (glx).

In any given lab of 30 clients between 1 and 5 will hang after they finish downloading the pxe image and start booting ubuntu. The little dots that show ubuntu is loading will continue forever. A bit of googling showed me that there had been a bug filed against the nbd server that sounded like the problem I was having. <a href="https://bugs.launchpad.net/ltsp/+bug/589034" target="_blank">https://bugs.launchpad.net/ltsp/+bug/589034</a> I downloaded the updated ltsp_nbd and followed the steps to disable the nbd_proxy but my problem wasn't fixed I also tried telling nbd to sleep for 5 seconds before continuing as method outlined here <a href="http://www.rickogden.com/2010/06/ltsp-part-2-configuration/" target="_blank">http://www.rickogden.com/2010/06/ltsp-part-2-configuration/</a> I haven't enabled NBD in my lts.conf file so maybe I am barking up the wrong tree here. Can anyone give me some guidance? Thanks!
