At the bottom of this Email is the result of the first LTP pass  
(started from dohell, started from xeno-regression-test). I never got  
so far with just the SD card in the panda (I ran exactly the same ltp  
test as before). LED2 is still constantly on, but the system remains  
responsive over wifi, ethernet and serial. Max latency is ~7us and  
worst latency is ~18us. Will post the final output ASAP.

I think from the results and the other reports on the mailing list I  
think I might be well off using this kernel as a base for our open- 
source/-hardware DAQ project.

Thanks a lot Gilles!
