Can only boot with -f since 10.8.2 install

[haynzee]

Hi all,

Today I decided to take the plunge and update 10.8 fully working to 10.8.2. At first it wouldn't boot at all apart from safe boot. After replacing the AppleACPIPlatform.kext with the old one from 10.8 as seen in this thread:http://www.tonymacx86.com/os-x-updates/76154-asus-p67-updated-10-8-2-cannot-boot-without-safe-mode.html I was now able to boot fully into the OS but only with the -f flag

If I don't use -f I get a KP with the following error:

Unable to find driver for this platform: \"ACPI\".\n"@/SourceCache/xnu/xnu 2050.7.9/lokit/Kernel/IOPlatformExpert.cpp:1546

Any ideas what could be causing this? Also is there any long term problems using -f?

Thanks

Pretty sure this has to do with kext caches (as -f disables them, or does it? not sure on lion/ml).
Did a bit of googling around on how to rebuild it and I think this might help: http://www.insanelymac.com/forum/topic/281181-usekernelcache-and-f-flag/
