Hi,

I just wanted to add one more data point I observed myself.

I had a similar error on my RPi 4B as described in the initial post when
using ZFS _on GELI_ on an USB3 attached SATA-SSD. After switching to
plain ZFS on USB3 on the same device it magically started working. ZFS
on GELI was only working on the USB2 ports. Maybe the errors are
related?

My dmesg dump from the time when it was not working:

As I said, I switched to plain ZFS on the USB3 attached disk and
everything works. (I am using ZFS encryption available since FreeBSD 13
without issues.)


Kind regards,
Stefan
