Look like you are getting garbage values because instructions are being
executed in the wrong sequence. Check if you are handling dependences properly.
One way to debug this is to compare the Exec trace from an O3 CPU without your
modifications, with the one you have modified. Another way to debug this is to
use the checker CPU.
