The thread demos work for me too - but the results look suspect.  For 
example, the multi-thread one showing threads 0 and 3 running several 
thousand times, but threads 1 & 2 running just a few times.  I would 
expect to see a more even distribution?

A thought - if it's locked up this hard, it must be somewhere in the 
kernel (or indeed my suspect semaphore handling) - otherwise interrupts 
should still be getting through.  I'd get out the xmd/mdm debugger and 
see what's going on.

Cheers,

John
