    Zenith II Extreme Alpha instability and restarts with BIOS 1603

    My system has ben running perfectly stable with the following hardware:

    MB: Zenith II Extreme Alpha
    PROC: TR 3990X
    RAM: 128GB G,Skill Trident Z 3600Mhz

    I multiboot diferent OS's mainly Windows 11/ Proxmox 7.1 / VMware ESXi 7 and had been fine since I built the system almost two years ago and about 8 months with BIOS 1502.

    Since the update to BIOS 1603 with AGESA I'm having spontaneous shutdowns and restarts without any pattern and with any of the OS I boot, in Proxmox (Linux) I can see the following messages preceding the crash:

    Apr 21 10:46:55 pve3 kernel: mce: [Hardware Error]: Machine check events logged
    Apr 21 10:46:55 pve3 kernel: [Hardware Error]: Corrected error, no action required.
    Apr 21 10:46:55 pve3 kernel: [Hardware Error]: CPU:0 (17:31:0) MC25_STATUS[-|CE|MiscV|-|-|-|-|CECC|-|-|-]: 0x98004000003e0000

    Apr 21 10:46:55 pve3 kernel: [Hardware Error]: cache level: RESV, tx: INSN

    Reverting to BIOS 1502 makes the system rock solid and no unexpected shutdowns/restarts.

    Someone have the same problem?

    Is the any way to open a ticket with Asus to help in troubleshooting it?

    I started experiencing TPM related issues after upgrading to 1603. Gonna revert soon I think!

    No issues at all here.

    Seems something related to the voltage control: undervolting a bit the SoC and the processor core, is stable like in the previous version.
