Hello, I have intel N100 and have this warning:

Is it possible to do something to make this working?

@Antibiotic said in PMC warning:

intel N100

It should work.

[Antibiotic]

@Gertjan Than why this warning exist?

[stephenw10]

The N100 seems plagued with problems but I'm not sure if that's actually anything to do with the platform or just that they seem to be favoured in as-cheap-as-possible chinese boxes with half-baked firmware. Particularly the power management seems incredibly variable from the reports we've seen on the forum.

But that's unlikely to be anything to do the PMC. It looks like that code doesn't yet know about the N100 specifics. I wouldn't expect that to be an issue though.
