Hi all,

I'm trying to troubleshoot an issue that crashed our host and trying to determine if it could be caused by the amd64-microcode package.
In the changelog for amd64-microcode I see the following message:
Code:
  * WARNING: for proper operation on AMD Genoa and Bergamo processors,
    either up-to-date BIOS (with AGESA 1.0.0.8 or newer) or up-to-date
    Linux kernels (minimal versions on each active Linux stable branch:
    v4.19.289 v5.4.250 v5.10.187 v5.15.120 v6.1.37 v6.3.11 v6.4.1)
    are *required*

What it does not mention is what could happen when not meeting these requirements.

We now encountered a crash of the hypervisor and BMC logs mention a unrecoverable CPU error. It may be a faulty CPU but I'm trying to rule out an issue with the microcode.

Digging a little bit it seems that specifically commit ID a32b0f0db3f3 has to be applied to the running kernel.
I found that it was applied here: https://git.proxmox.com/?p=pve-kernel.git;a=commit;h=4696b978f7702bd88c6773a1853b4cf928481a26

However, I cannot find if the current Proxmox Kernel ( proxmox-kernel-6.2.16-15-pve ) has this change applied as well. Checking for a changelog fails as well:
Code:
apt-get changelog proxmox-kernel-6.2.16-15-pve

Does anyone know whether the change was already applied to the released Proxmox Kernel?

Thanks!
