Problem with wake and DSDT

Hey guys,

I´m having a problem with my DSDT. My machine goes to sleep but when I try to wake it up again the fans just start spinning for 2 seconds and then stop again, start again, stop again and so on. I just cant imagine what the problem might be.
I had the same problem with SnowLeopard but there it only happend every 20th time or so.
Now, that I´m using 10.7.1 it happend every time.
I also changed my graphics card from a 9800gt to a 4870 with the update to Lion. Don´t know if that has something to do with the problem. But I don´t think so.

My system
Gigabyte GA-H55-USB3 Bios F10
I5 760
16GB RAM 4x4GB
Radeon 4870 1GB
BeQuiet 460 Watt
2 SATA HDDs

thanks

Have you tried SleepEnabler.kext? It worked for me in SL 6.8. There are lots of sleep fixes out there on the forum and some special threads dealing with the issue.

Yes I tested several Sleepenable.kext files. From kext.com for example. But I´m getting a kernel panic with everyone of them.

Well, I upgrated to 10.7.2 and now sleep and wake is working.
But I still don't know why.
Interesting is that I had to Installation Windows 7 an a second harddrive and I'm having exactly the same problem with sleep and wake there that I hat with 10.7.1
The amachine goes to sleep but doesn't wake up. The Fans Start Tuning and stop again.
I'm really curious what the problem mighty be. Seems to be a hardware problem I think...

dead thread i know but i am having the EXACT same issue with my system. except in 10.6.8 or any version of snow leopard or Lion. I havent tried 10.7.2 yet. thats my plan 4 tonight
