I'll look into this more later today, but wanted to run it by you in
case you have any thoughts.

Can you apply this patch [1], and let me know if you see the additional
trace?

I applied the patch, the following is the (unchanged) output:

Can you test with this one [1]?

With that patch applied, my Ci20 successfully boots again.

Thanks for looking into it :-)
