Hi Mammoth, kizwan
I tested things more than once before posting. I found my problem in graphic part of the dsdt causing the freeze in my system.
Without such modification,i have no hangs/freezes . And i tried to EnableGraphics inside com.apple.Boot.plist and qe&ci are still not active. I even tried putting my nvcap, but it's exactly the same.
My LPC device is loaded fine (i checked the ioregistry). Tomorrow i will post my ioreg and you can give a look at it if you find something strange.
I also have my cpu i7 720qm shown as 3 ghz i7 .
But the most important part to be fixed is the graphic part.
Is it so important to install MacBookProUpdate1.3 before 10.6.4 update ? Have you ever checked nvidia website for their latest driver downloadable for 10.6.4?
Thanks for your replies/time to help me fixing my probs with dv8. It's an amazing laptop and i'd like to have it fully working with Snow!!
I don't know whether this has been mention before or not but does AppleLPC.kext loaded? If it is not, LPC device in DSDT need to be patched. AppleLPC is useful in making the CPU run much cooler. Also do a cleanup in the DSDT such as removing IRQ from RTC, TIMR (or TMR) & PIC (or IPIC) device. There has been a report that this little cleanup does solved the random lockups or KP on i7-720QM powered notebook. Can you or anyone who use R2 DSDT, post here the ioreg dump (using IORegistryExplorer application)? Thanks.
