Please note that the line `arm_64bit=1` (in `/boot/config.txt`) **is necessary** to boot this kernel. This had me scratching my head for a while; ~~it was not necessary on 6.16.1-1, but became so by 6.16.5-3~~.

Now that I have solved that problem, I can say 6.16.5-3 works great.

Edit: see the following.
