I never found a fix.
I recommend that you get a different motherboard by another manufacturer.
1. Do NOT recommend people get another brand of motherboard, that is first and foremost because I have used Gigabyte, Asus, Asrock and MSI and they all have this problem.
2. This problem is NOT a manufacturer problem from what I can tell, in my 30 motherboards of testing I have found that only one ( Asus P8Z68 Deluxe and only by sheer luck ) gave me any information and that information was the boot loop into memok reset into Code 78 Indicating what I thought all along was the problem, ACPI. This is a chipset issue, it wasn't right the first time and its not right now, Intel fubar'ed this one.
3. I have NOT found a resolve for this, once it does it the loop will never go away perfectly, I have updated bios', installed 1 - 3 GTX 580's, 1-2 GTX 590's, 1-2 6950's/6970's almost every configuration and brand of memory, SSD, video card and more and nothing makes a difference. I have also changed or ( for the guy mentioning disabling the Marvel chipset ) disabled every and I mean EVERY single type of hardware setting inside the bios' in an attempt to fix this and nothing. The last build the Asus Deluxe all the ACPI options inside the APM section were disabled Fyi so the hardware attempting to use it seems ridiculous in the first place.
Any questions about what all I have or have not tested just ask, but its basically everything, still willing to listen to suggestions for setups/what to check further to find the solution, but I would bet the solution is to tell Intel where to stick this chipset.
As another fyi I should have known months ago when I started this that the fact that I can't put my computer to sleep and have it wake up without a total reboot should have clued me in.
