these patches in clover.config are known to cause issues in 10.10.3 on certain machines you can try removing them especially second stage patch.

Remove AppleHPET kext from /S/L/E (keep a backup somewhere), then rebuild cache with Terminal commands:

sudo touch /System/Library/Extensions

sudo kextcache -Boot -U /

 

You should be able to follow most of the stuff that apply to the E6440:
