Awesome. Thanks for the info sk1nhdd33t

Will patch up accordingly and let everyone know how it goes (if anyone cares).

Well I've hit the wall...again. I've been trying to update to 10.6.2 and it kernel panics almost immediately. I've lost sound and when I remove sleepenable.kext for some reason I lose my ethernet connnection as well.

I'm not too sure where I went wrong but it's 1:30am and I need to work in the morning. Dammit.

I removed sleepenabler.kext, rebuilt the kext cache, downloaded and installed the 10.6.2, added in the new sleepenabler.kext and then rebuilt the cache.

I use the V1 motherboard, your signature appears to be V2 so wonder if that is anything to do with it?

Black screen and VGA
 

I have the same problem as you. I cloned my flawless system but the newer setup has only a VGA monitor (1280x1024). Here are my observations:

If I use the original DVI/HDMI/VGA (1920x1080) monitor using DVI or HDMI connectors, it works fine.

If I use the VGA monitor, I get the funny black screen.
If I hit the power button for a very short period, I see the login screen for a fraction of a second and then the machine goes to sleep.

If I hit the power button or any keyboard key or click on the mouse, the machine wakes up and I get the beautiful login screen and things work.

Idle sleep does not seem to work. The displays shuts off but the machine keeps on running. At least the fans were running.

If I force the system to sleep via the menu or the power button, the system DOES go to sleep like it should and wakes up as it should.

Switching to the DVI monitor fixes the login and sleep problems.

I have this wild conjecture that when I use the VGA only monitor, the display system is actually trying to use the DVI port and fails. Hitting the power button may cause it use the VGA port. But this may be my conjecture at 2:27 AM.

Thanks so much, i guess my fault was the boot order because that was the only difference. Whatsoever, now it works like charm! Thanks again.

Not too sure either. When I look at the KP screen I see that it is the sleepenabler that is causing the problem. I think that part of the problem was that I tried to load the new sleepenabler kext before doing the upgrade so that I hopefully wouldn't lose ethernet. I must be doing something incorrectly because it's my understanding that sleepenable has nothing to do with ethernet. Gosh this is as bad as when I would spend hours trying to configure early linux distros.

My next step is to download the 10.6.2 combo file and do an offline installation. I'll see if that works.

If anyone is looking for the offline files they can be found here.

Another Lurker my upgrade 10.6.2 experiences and method=fail
 

I have a 10.6 system following this guide. I never used sleep enabler though.

Some people might be interested in the way I test updates now. I use carbon copy to clone my current drive (i was made following this guide). Just reinstall chameleon bootloader ( here ). That will give you a perfect copy of your system that is bootable. boot into the new system from bios. try your upgrade configuration. If and when it doesnt work. go to carbon copier again clone your working drive again, this time it wont take very long to clone your drive since it compares files before it moves them. it is awsome.

I am trying to update this system too and I am having trouble. I have gotten 10.6.2 to work.

Update
add new sleepenabler (i didnt have old one)
delete extentions.mkext
rebuild as advise earlier in thread.

got it to boot buuuuuuut

its weird. it doesnt sleep like my current system does. ethernet issues. etc...

i'll keep a look out and I can try a few tweak everyday till i get it. with this carbon copy work flow it is easy to test out changes. good luck. look forward to other results.

How!? How does one rebuild the kext cache?

A great suggestion. I've been doing the same thing but have been using Disk Utility. I ran into a problem where it didn't image properly. Do you have Carbon copy on a bootable USB or disk?
