dmesg from successful boot (with module blacklisted)

On my MSI Alpha 15 B5EEK laptop (AMD Ryzen 7 5800H), the system fails to boot
on Linux 6.15 due to a general protection fault linked to the amd_sfh (Sensor
Fusion Hub) module.

The error occurs early in the boot process, and results in a kernel panic.
Booting with the amd_sfh module blacklisted resolves the issue. Additionally,
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 — the
system appears stable and fully functional.

**Reproducible:** Always  
**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 — issue no longer occurs
