AMD Ryzen PRO 6860Z powered Lenovo Z13 notebook with Microsoft Pluton co-processor can't boot Linux operating systems
Phoronix reports that AMD powered ThinkPad Z13 laptop featuring Ryzen 6000 PRO Zen3+ series has problem booting Linux operating systems. This has been discovered by Matthew Garrett who shared the news on his website.
This laptop is equipped with Lenovo exclusive AMD Ryzen PRO 6860Z processor with built-in Microsoft Pluton security co-processors. This is a dedicated chip that is supposed to increase security for Windows systems by verifying UEFI certificate keys. The problem is that it only trusts Microsoft's key, not any 3rd party UEFI keys that are used by various Linux distributions.
This essentially means that Lenovo ThinkPad Z13 simply cannot run any Linux system. This laptop ships with Windows 11 by default and while there is no mention of Linux support anywhere, one could also argue that nowhere does it say it cannot boot Linux (and yes we have checked various official specs and press releases).

So, the DEFAULT configuration doesn't boot to Linux? Ok. Then change the setting.
This reeks of FUD to me.

This doesn't seem to actually have anything to do with "Pluton", the "AMD Ryzen PRO 6860Z", or the "Lenovo Z13" notebook specifically. Furthermore, the assertion that "this essentially means that Lenovo ThinkPad Z13 simply cannot run any Linux system" is demonstrably false.
The requirement to manually turn on "Microsoft 3rd Party UEFI Certificate" support applies to ALL Microsoft "Secured-core specification PCs."
Now, of course you can complain all you wish about the fact that Microsoft is requiring manufacturers of all PCs that come with Windows pre-installed and the "Secured-core PCs" moniker attached, to ship with their Microsoft 3rd Party UEFI Certificate support disabled by default, but it is total FUD to appear to blame Lenovo or AMD since this applies equally to a Dell-branded PC or whatever...
It is certainly highly disingenuous, at best!

... is ALSO demonstrably false!
They certainly couldn't have tried very hard to find any sort of OS list specification, since the actual specification PDF for the Z13 series clearly states:
Fud, fud, fud, fud, FUD!
