After an "apt upgrade", the kernel was switched to "Linux 6.6.16-current-sunxi64" (Armbian 24.2.1 Jammy).
On the WiFi side, no problem, but for Ethernet, it no longer seems to detect the link.
So I downgraded to "Linux 6.1.77-legacy-sunxi64" with armbian-config. After this, the Ethernet works again.
Do you have any idea where this could come from? And if this can be fixed in future versions?
