I grabbed the "Armbian 25.8.1 Bookworm Minimal / IOT" image from https://www.armbian.com/tinkerboard/, landed it on a microSD card, booted it, and ran
apt update
apt upgrade
apt install linux-headers-current-rockchip
apt install zfs-dkms zfsutils-linux
This gets me linux-image-current-rockchip 25.8.1 (kernel 6.12.44-current-rockchip) and a module built from zfs-dkms 2.3.2-2~bpo12+2. So far so good. And then I ran
modprobe zfs.ko
and was rewarded with the following panic in the kernel's module loader:
[ 1128.728803] spl: loading out-of-tree module taints kernel.

I have been unable to find debug symbols or a way to get an objdump of the loaded kernel (probably I am just missing something). Please advise what more I can tell you to be useful.
I am unable to run armbianmonitor; after the above, lsmod hangs, and upon boot, the machine attempts to load zfs.ko which again crashes as above and userspace is pretty direly stuck.
FWIW, I am happily running ZFS on a Tinkerboard with an older system, specifically linux-image-current-rockchip 24.11.1 (which is kernel 6.6.63-current-rockchip) and zfs-dkms 2.2.2-0ubuntu9.1.
