Hi, thanks for reply.
Ok we can wait your vacation for the GUIDE!

Concerning your indications, are you referring to SL or X.5.8? Just because I'm quite happy with 10.5.8, the only point is to be able to use all cores, off corse.. Right now I'm using your DSDT, as you posted in other topic.

Best

Thanks for the patience.
I use my DSDT with SL, so you probably can, try it on a different partition.
Are you using the one I posted as the "cleaner" one?

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

I really don't know what to say! If I had the PC in front of me I might be able to do something, but not from here. The only thing I can guess is that native power management somehow doesn't like your card.
WAIT: I JUST FORGOT SOMETHING IMPORTANT THAT I THINK I NEVER MENTIONED IN THIS THREAD (I took it for granted): have yo set DropSSDT=Yes in com.apple.boot.plist?
I don't think you should even be able to boot all cores without it, but hey, it doesn't hurt to ask.

I have found the wifi-crash soltution. Maybe some one interested because it seem that a lot of people with atheros-based PCI card are experiencing problems.
Now from an old post, I found the IO80211Family.kext from a 10.5.1 iatkos DVD, the solution in order to use my d-link DWA-547 with all cores enabled. Now the system is stable.

Still need investigating for sound and sleep but now the situation is much better!... thanks to all.

Sound you can find on this thread, sleep was a no go with my old motherboard, I did a RMA on it because it didn't work in mac or windows (S3 that is) and some RAM issues, I'll see what the new board brings. Maybe I'll even have sleep...

Hi

about sound, no way for me.
I have your last DSDT and the kext you post attached, but no. I can have audio only if i install Voodoohda.kext but only i I boot in cpus=1.

I have DSDT at the root and all kext in the extension folder. No extra folder.

No extra folder? I don't get what you mean, kexts go in drive/extra/extensions or drive/extra/extensions.mkext.

Thanks for the help, I was able to successfully modify my DSDT!

I'm a bit confusing regarding kext and locations of them.
By the way, as soon I would like to try a new SL install on a second drive. Some one here have been success with sleep on this board? Tks
