Tested coreboot 17848b65c38c32fa9630925ca8a15203a0617788 with EDK2 92533b23fb93259b20661b6534109e9f59384e93 origin/uefipayload_202306 and SMMSTOREv2 works fine on Lenovo X220 (SandyBridge). What's a STM/PE?
This Issue is about STM/PE a Supervisor/Hypervisor for SMM System Management Mode, if you can test too can be good, just enable STM option in Menuconfig and enable STM/PE Hypervisor

* Author: Elias Souza * Status: Needs Testing * Priority: High * Category: coreboot common code * Target version: 4.21 * Start date: 2023-10-09 * Affected hardware: is necessary testing in newest hardwares include Haswell and Kaby Lake, but idk if affect other platforms different than Sandybridge * Affected OS: All ---------------------------------------- For some reason the SMMSTOREv2 looks to break SMMSTORE support in STM/PE during boot.

* According with the reddit user crazyfox-ua " The same for me on T440p & X230t (both with edk2) - just blank screen. Disabled STM brings both laptops back to life. CB logs says nothing strange IMO (last record is "[DEBUG] Jumping to boot code at <hex here>".
Is necessary to test if others payloads is affected by this bug
