Hi all,
I upgraded my D430 from 10.6.7 (EDP 1.8) to 10.6.8 today knowing a few tweaks would be needed after the update. So, using some info i found in jumpmans topic (D430 does not boot after upgrade to 10.6.8) and poldas topic (After update to 10.6.8 I lost wi-fi and ethernet) i've messed up... The laptop kernal panics on boot with:
panic(cpu 0 caller 0x563ebd): "Unable to find driver for this platform: \"ACPI\".\n"@/SourceCache/xnu/xnu-1504.15.3/iokit/Kernal/IOPlatformExpert.cpp:1387 etc. etc.
If anyone can help from just this info, great, otherwise i think i can explain what i have done if anyone can help reverse/fix.
Following upgrade to 10.6.8 the laptop would kernal panic on boot. From jumpmans topic (D430 does not boot after upgrade to 10.6.8) i found i could boot successfully by specifying pmVersion=0 at the Chameleon boot prompt and using Bronxteck's advice to use nawcoms '10.6.8 sleep enabler' (and rebuild mkext) . The laptop now booted but was slow to respond, almost always had 100% cpu usage, ethernet and wifi did not work.
I then found from poldas' topic (After update to 10.6.8 I lost wi-fi and ethernet) and i repaired my disk permissions, removed and re added my Airport, and updated my dsdt.aml file to replace _ADR with _UID under Device (PCI0) section.
Then i replaced the AppleACPIPlatform.kext and IOPCIFamily.kext with the ones from 10.6.7 and used Kext Wizard to repair permissions and rebuild my kextkache. Reboot > KP
Any help really appreciated. Thanks for taking the time to read this.
