Trenchboot AEM crashes on Lenovo Thinkpad T14 Gen 1 (Intel)

[TommyTran732]

Affected component(s) or functionality Trenchboot AEM.

Brief summary On my T14, after booting Qubes with AEM is selected, Grub will attempt to load in the SINIT file CFL_SINIT_20221220_PRODUCTION_REL_NT_O1_1.10.1_signed. As it is loading it in, the system reboots, and if I choose Qubes with AEM again, I get the following error:

I have verified that

• The Thinkpad is booting in legacy boot mode
• The SINIT binary one is the correct one (the CPU is an i7-10610U)
• Intel TXT is enabled
• Hyperthreading is enabled in firmware settings (Lenovo firmware does not require Hyperthreading to be enabled for TXT to work, but I know on Dell firmware it is a requirement so I kept it enabled there)

Version p4-rc1

To Reproduce Steps to reproduce the behavior:

1. Import the signature at https://dl.3mdeb.com/open-source-firmware/QubesOS/p4-rc1/RPM-GPG-KEY-aem to rpm in dom0
2. Add the repo at https://dl.3mdeb.com/open-source-firmware/QubesOS/p4-rc1/ to dom0
3. qubes-dom0-update
4. qubes-dom0-update anti-evil-maid
5. Add the SINIT file to /boot, setup the TPM and installing AEM to the boot drive
6. Reboot

Expected behavior The system boots properly and I can setup AEM.

Actual behavior The system reboots and I get TXT_ERRORCODE reports failure: 0xc00014f1.

With the latest build (4.2.1), it just reboots into a blank screen and does nothing
