Your problems appear to centre around these steps:

which is to say that a TFTP request for the image goes out at 12:00:00.
You then have a 7:39 minutes before an nbd_server read timeout.  Something
in there is going wrong.

As a start, I suggest you take a backup copy of the file below, then edit
it, removing the words quiet and splash.  This will give you a more verbose
boot process so you can see where the pause is.  You can then reboot and
let us know how you get on.

   /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default

As a second suggestion, I'd reboot again with the following tcpdump command
running on the server.

  sudo tcpdump -i eth0 ether host 00:08:a1:48:0a:14

Then you'll have a full list of all frames that went back and forward
between the thin client and server.  This may help to show the issue.
Though hopefully it'll already be apparent after the first test.
