Phoronix [phoronix.com] 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 [dreamwidth.org].
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).
