on my samsung np200 laptop I'm able to boot WITHOUT the NullAppleIntelCPUPowerManagement so the sleep is working properly
but the pc wakes up immediately
I wrote this command on terminal
syslog -k Sender kernel -k Message Req Wake
and Wake Reason is GLAN EHC1 EHC2
So I applyed EHCI patch and then sleep works, but in a very strange way: I have to press the power button several times and then i
have to press a key on the keyboard to enable the screen; also when i close the lid its not going to sleep..
What else can I try? Maybe I can just edit _PRW and _PSW methods from GLAN and EHC1 EHC2?
