a bit more on info. running two single cores fah also makes no freeze.
just appears wierd in top:
1983 matheus      15  44    0   632M   544M ucond   0   0:00 135.25% VirtualBox

but thats ok :)

performance is good, not sure when two running, but one was s fast as real machine.

next step for me is see performance in smp mode and make it not freeze pc :)

thanks,

matheus
