Hi, yes I'm using your last posted DSDT. Now I'm finally found the problem I have with all cores enabled. When I use airport enabled, the system crash. I think can be some kind of atheros kext, but if you have some suggestions I appreciate.
If I boot with cpus=1 no problem, I can surf with wifi enabled ( i have Dlink 547). If I boot with all cores, when I start using the wifi, crash!

spec: X.5.8 - asrockX58extreme - i7 920 - nvidia 9500gt - 2gb dominator - 2 x 500 sata2 - dlink 547
