The default latency-test tries to run a 25uS base thread.  Since the IRQ
response time on the ARM is longer than that, it pretty much kills the
machine.  Try:

  latency-test 1ms

Easy?  Not really.  I'll see if I can dig up data on the part you listed
and add the temperature table.

I'm not really fluent in python either, but it's not too bad.

Hmm...looks like Semitec doesn't provide detailed temperature tables,
just an R25 and a Beta value.  I'll see if I can't code something up to
use these and make a new thermistor table.  Then it will be easy to add
other thermistors that just have a Beta number.
