I can't make them at the moment, because I don't have the UART adapter.
But it's simple to reproduce.
Just do a full system upgrade and the 6.6.68 kernel will segfault on the next boot.
I've flashed: Armbian_25.2.0-trunk.193_Odroidxu4_trixie_current_6.6.65_minimal.img to my eMMC.
It boots fine, but after a "armbian-upgrade" it will give a kernel panic upon reboot.
I think the new kernel is borked.
