Still waiting for root device after 10.7.4 update

[ttimpe]

Hey guys,

I just updated to 10.7.4 by using the dmg. Then after the install was done, I ran MultiBeast to rollback AppleHDA. After rebooting with the DropSSDT setting in my org.chameleon.boot.plist, I now only get a "Still waiting for root device".

Do I need to reinstall the SATA drivers?

My system:
GIGABYTE GA-Z68XP-UD4
Crucial M4 SSD connected via SATA3

My BIOS seems to be fine and didn't reset anything, AHCI is still enabled everywhere!

What is the problem?

Thank you in advance

Tobias

I checked via single-user-mode, and I already have JMicronATA.kext installed, so that doesn't seem to be the problem.
