10.6.8 Boot issues

[sketchy]

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.

This topic can now be closed please mods.

 

Back up and running on 10.6.8 with wifi (including USB and ethernet which some seem to have had issues with). Found that i did not need to edit the smbios.plist.

 

IIRC i resorted to:

 

Install of 10.6 (kept user account and settings amazingly)

Installed and ran EDP 1.9

Ran software update straight up to 10.6.8

Lost wifi etc (but with EDP 1.9 no 100% cpu usage)

Delete the file NetworkInterfaces.plist from /Lybrary/Preferences/SystemConfiguration/

Delete Network Interfaces from System Preferences/Network

Used Kext wizard to install AppleACPIPlatform.kext and IOPCIFamily.kext from 10.6.7 (i did not have a backup from 10.6.7 but you can google for these)

Overwrite the Apple80211Monitor.bundle from 10.6.7 (i did not have a backup from 10.6.7 but you can google for this)

Ran the kext wizard to repair permissions etc. YOU MUST DO THIS to correct the permissions (of a fair few things that i'm yet to understand) of Apple80211Monitor.bundle i think when you put this back you are missing SYSTEM and WHEEL.

Ran EDP 1.9 again

Reboot to KP. Force power off and back up and running on 10.6.8 with wifi

 

Thank you people of this forum, you helped me out loads.
