It works fine on 6.12.12 and 6.13.1, but with 6.14-rc1 I don't see these last several lines of output as in your case.

This is a known issue. A revert has been submitted: https://lore.kernel.org/r/E1tfeyR-003YGJ-Gb@rmk-PC.armlinux.org.uk -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
