So, if it says "Error: IOCTL_MEI_CONNECT_CLIENT receive message. err=-1", what does it mean?

Tried it on i5-6260U, should be new enough to have the thing.

The issues page has a report of the same error (as does my i5-6600) and the author says:

>Ok, I'm /inclined/ to believe that this indicates that the system doesn't implement AMT at all, but I'll try to do some more research.

I got this message on a system which has a Core i7-4510 CPU; this is not on the list of systems with "vPro" technology. I've seen referenced as another name for the vulnerable component --- but given the marketing-spawned confusion around Intel CPU nomenclature, I can easily imagine someone (perhaps me!) getting confused on the point.

Search for "vPro" systems here: https://ark.intel.com/Search/FeatureFilter?productType=proce...

This isn't that helpful because you need a vPro-capable CPU and the proper chipset and AMT firmware to be vulnerable.

Maybe the driver isn't loaded?

It is.
Upgrade your kernel, or build the kernel with the AMT module
4.10 is fairly new, and the amt mod is loaded
Cool. thx
