lucke77 Posted March 30, 2014 Share Posted March 30, 2014 Hello to all, I'll explain the problem... Â The machine is at the bottom, the Boot loader: Chameleon r2377 kext: fakesmc, applehda, GenericUSBXHCI.kext x USB 3.0, AppleRTC patched, patched AppleIntelCPUPowerManagement, AppleLPC ver. 1.5.1 ( test 10.6.8 ) Â So if I start with DSDT=NULL, the system is operating at 99% except for the audio and the absence of loading the kext: AppleLPC. The sleep function is activated after 20 seconds (so it works only in mavericks, but no problem) by pressing the power button or from: Apple Menu>Stop. Wake up fast without restarting. Problem is with shutdown for the absence of the DSDT . Â With patched DSDT (attached to post) with the essentials, without errors, to inject AppleLPC (3a18), and then loaded, when I try to go to sleep after 20 seconds the usb go in sleep but the pc stays on, to put him to sleep total I have to press the power button on the pc. Only a few times, repairing permissions and rebuilding the cache, the sleep works. Â It would therefore seem a problem with all'AppleLPC. I do not understand if I miss a fix in DSDT...? if there is a patch for this kext...? Â But does anyone know if it is essential to load at startup, the computer seems to behave regularly without it, including speedstep... Â Thanks in advance for the help...
