> Furquan, could you take a look please? If this is an issue there, I'd expect there to be similar issues on other Intel platforms.

it only seems to affect Haswell/Broadwell. I've tested from SandyBridge thru AmberLake, the rest have no issue. Skylake forward changed the EC SMI handling significantly.
