Public bug reported:

platform:  sharkbay platform with haswell cpu
symptom:  the eax, ebx, ecx ,edx values with cpuid eax=7 are all zero, this 
isn't correct on haswell cpu.

reason :  Before cpuid app executes cpuid instruction, it doesn't clear ebx, 
ecx and edx, this break intel cpuid instruction rule.
                 you can check cpuid instruction at :
