The error occurs early in the boot process, and results in a kernel panic. Booting with the amd_sfh module blacklisted resolves the issue. Additionall= y, the latest LTS kernel (6.1.x) works fine with the module enabled. System is running Arch Linux with linux-cachyos kernel 6.15.2-2. No critical side effects are observed when the module is blacklisted =E2=80= =94 the system appears stable and fully functional. **Reproducible:** Always=20=20 **Workaround:** Blacklist `amd_sfh` and rebuild initramfs Hardware: Laptop: MSI Alpha 15 B5EEK CPU: AMD Ryzen 7 5800H with Radeon Graphics BIOS: E158LAMS.10B (05/18/2023) Steps to Reproduce: Boot system with Linux 6.15 kernel Observe crash (kernel panic from general protection fault in amd_sfh) Boot with amd_sfh blacklisted =E2=80=94 issue no longer occurs --=20 You may reply to this email to add a comment.
