Plex Media Server on Ubuntu 21.10 with Intel 12th Gen (Alder Lake)

To all following here.

The root cause of the failures for all versions above 20.04/ ICR 21.49 has been identified.

In a nutshell, Intel changed the ICR API after 21.49 release.

If you compare their changes on github, you can clearly see where several function’s call args were changed.

They further changed from using “Version 11” of the API to “Version 12” after the 21.49 release. ICR was new to all of us for these new processors and it was already “version 11” ?

I don’t know the current status (I prefer not to interrupt if avoidable).

The only thing I am certain of is the team is now deep in figuring out how to resolve.
There are some questions to answer:

  1. Maintain 20.04/21.49 compatibility and ICR’s latest? (don’t think this is viable)
  2. Upgrade PMS to API v12 and have everyone update their ICR version to current (think this is better)?
  3. In light of the bugs in ICR, which is best for all processors ?
