<< Solved >> EHCI Controller unable to take control from BIOS

[gerodotfour]

Attempting a build for the first time - followed the guides for BIOS configuration. I set the install to verbose, and see it keeps hanging up here:

Pthread support ABORTS when sync kernel primitives misused.

USBF: 1.556 EHCI controller unable to take control from BIOS
USBF: 1.558 AppleUSBEHCI: unable to obtain ownership ...
USBF: 1.560 AppleUSBEHCI: UIMInitialize - Error Occurred ...

Any ideas? Need more info? Thanks!

Okay, found in another thread to get around the EHCI problem just use command line USBBusFix=Yes when you boot from UniBeast. I will post more later, there may be a problem I need to solve re: onboard video function.
