Boot issues with imx6

I'm not really sure what the problem could be but we currently have a pretty big problem. Basically our custom boards have a pretty low yield due to a very random boot issue. Everything from unrecognized instruction to the system just halting during the boot process. I included some outputs below. The failures are pretty spread out and the only thing i can think of is we have some bad CPU's or maybe ddr.
