Choose one: systemd-networkd, NetworkManager, or traditional /etc/network/interfaces . Do not use two to manage the same bond.
The error appears when the daemon tries to revert a bond’s or bridge’s custom parameters but finds that the operation is unsupported by the kernel or the interface’s current state. In essence:
After a kernel upgrade, some bonding parameters may have new valid ranges or changed behavior. systemd-networkd attempts to reapply the old parameters. Because the kernel now rejects one of them (e.g., tlb_dynamic_lb handling changed), the reversion fails.
Check your configuration files (e.g., /etc/network/interfaces or /etc/netplan/*.yaml ). Ensure you aren't defining the bonding parameters in two places. If the bridge configuration also tries to dictate bond settings, the kernel may throw this error when the bridge starts up. 3. Proxmox and Virtualization Hosts
Ensure the bridge-ports line for your bridge includes the bond.
