Okay, so just to be clear. You have installed OS X 10.6.2 using Chameleon 2 RC4, and not EFiX?
Did you use a standard 10.6 install, and then use software update to get to 10.6.2? (you would have to update sleepEnabler before rebooting otherwise you'd get a KP on restart)
Did you update your SleepEnabler.kext to the 10.6.2 compatible version?
Yes it is not. The air gap is sufficient, I'm sure.
And, one more time, is your EFix dongle not plugged into your USB and on the other side of the room, under the couch?
Since everything was 'virgin' I didn't go through any trashing rituals. I did build a brand new session, and now I have tried playing from both SATA drives and a Firewire drive, no difference.
As far as Protools, of course you have trashed preferences, rebuilt databases, etc, right?
This is happening in a completely fresh session?
Where are your files playing from? Which drive and bus are they on.
Yes -- it is like that looping right before a crash that used to happen sometimes, but it will stay responsive... I can even solo and mute tracks, whatever.
Your problems sounds like it's either disk or memory related. Pro tools will still be visually okay in such an instance because it is reading the waveform and meter info from wave cache.
The only time I have ever seen this type of issue, is right before Pro tools is about to crash, but you say your system will play like this and then continue to function logically?
Check this thread. I know this for the EX58 UDR3 Mobo, but installation should be the same, except for a couple of kexts.
Check your Bios for memory and Sata settings.
I would erase the system drive and do a completely fresh 10.6 install using PC EFI 10.3 (I haven't tested 10.5 yet).
Test this setup with your system and just the core card. Should be cool.
Add a card at a time and continue to test.
As an option update to 10.6.2.
I only updated because I wanted to use the new Apple bluetooth magic mouse, which require 10.6.1 or later.
Oh, I also just realized that PC EFI 10.3, as used in the X58 Mobo Script, uses Chameleon 2, and not the latest 2 RC4 update that is in PC EFI 10.5 (I believe) so this could be your problem?
I followed an install method by aserebln.blogspot.com and I don't think PC EFI was involved, though I have subsequently tried different versions of the boot file.
I think I must have put something in my DSDT that is throwing things off.
Today I started over and used older methods (no DSDT file) and installed Chameleon 2 RC2 and some kexts and BINGO, my 10.5.8 partition that works with EFiX now works with Chameleon.
So I know I'm at least good for Leopard. When I have the will I'll probably go back over the RC 4 with DSDT procedure to try and get SL up.
Thanks for your thoughts Noizyboy. I'll keep you all posted.
