Ok, now I have setup again debian 6.0.1a and compiled the 2.6.39-rc6 
kernel but with the hyper-v staging drivers from ubuntu kernel 2.6.38-8 
source (just replaced the hv directory, I know maybe it's dirty :) ). 
But now all is working fine! I have now a debian system with kernel 
2.6.39-rc6 with all integrated components running..looks that the 
hyper-v modules in the ubuntu kernel are more stable that in the newest 
official rc kernel?!

Regards
Juan
