Did you fix your ME issue yet? it might be futile to make assumptions<br>
about the hardware if the ME is no running correctly.<br>
<br>
If you are sure your ME is doing well and all four functions above fail<br>
individually, there may be multiple issues. I'd start by diving deeper<br>
into those function and find the first hardware access that makes it<br>
hang.<br>
<br>
The first function enables SMIs based on devicetree settings. Make sure<br>
these settings match your hardware (or set them to zero if in doubt, to<br>
rule them out).<br>
