Proxmox - Troubleshooting - Kernel Panic

Proxmox freezing with Kernel Panic.

Solution

Seems linked to a specific VM.

Changing disks to use

Edit /etc/apt/sources.list, and add in

<file bash /etc/apt/sources.list> deb http://ftp.de.debian.org/debian bullseye main non-free </file?

Install the AMD Microcode:

apt update
apt install amd64-microcode

Reboot.
