So when the bad clients fail, they are inaccessible via Ctrl-Alt-Fn and
ssh. But if you set up rsyslog this will forward to the server any
syslog entries the clients generate before they freeze. Might give you
some clue.
On standalone PC's, I have seen bad optical or floppy drives cause an
otherwise good machine to fail at boot. If these clients have any
optional components like that which can be removed, that idea could also
be tested.
Since this is also a rather big issue, I would consider setting up a
different test LTSP server in a different version and/or distro. If it
fails similarly there then you have further confirmation that it's a
failing-hardware issue with the clients.

We've done the following tests and it could be interesting.
We've two school rooms with the same hardware (server and thin
clients) in different cities.
School Room A: 15 thin clients.
School Room B: 20 thin clients
We've done lots of test and we can conclude the following: when a
terminal works fine it always works but when a terminal fails it
starts one time of 20 more or less. In our tests we've around 87% of
"good" terminals and a 13% of "bad" terminals.
Room A: 3 thin clients fails. 3 "bad" clients and 12 "good" clients
Room B: 4 thin clients fails. 4 "bad" clients and 16 "good" clients
We've even test "bad" thin clients of Room A into RoomB and it also
fails.
We now understood it could be a hardware issue which generates Kernel
Panic randomly in "bad" clients so it's imposible to access the system
when it's frozen, but it's hard to explain to my client because the
"bad" thin clients can start an Ubuntu 12.04 from USB and the
Fujitsu's SO included in the SD card. Also the client starting the
boot splash.
Any ideas? Any approach to debug?
Thanks guys!
