So now a summary:
* Error only with  one specific hardware model, a HP T5540 Thin client.
* Version 6.03-pre9 > not working
* Version 6.03-pre14 > working
* Version 6.03 final > not working
* Error message is
     Failed to load ldlinux.c32
     Boot failed: press a key to retry, or wait for reset...


What is in the logging of the (TFTP) server?
Do you see the request for 'ldlinux.c32'?
