I used to have P8P67 / 2600K / HD6970 / Apple Cinema Display, system running 10.9, everything was working with dsdt i dumpped with everest under windows. generated ssdt with revogirl's script.
iMac 12,1 smbios.plist
recently, I replaced my video card with Two MSI R7850 Twin Frozr 2GD5/OC Radeon HD 7850 2GB crossfired. and added the device id into retail kext, then video card is working. to make it 'perfect' I also inject rampagedev's 7xxx dsdt patch into my DSDT, in IORegExplorer, under PEG0/PEPG, it show up under display@0.
however i'm starting to have sleep & wake problem after this. it looks like it will go to sleep, ether with power button or waiting, however after it went to sleep like 2,3 minutes, the computer will wake up when i press keyboard or mouse, yet the display will not wake up. And I have to power cycle (unplug the power cord from tower) in order to get display back. reset button will reboot the computer but I won't get any video on display.
I attached my /Extra..I did some clean up in DSDT.aml, but there are still tons of junks in there, probably not gonna affect anything...what do I need to patch to resolve this problem?
Thank you for helping.
