This is exactly what I am getting (just sent another message on the list about it).

I know you later mentionned that disabling ZYNQMP_PM_DOMAINS made it work. In my case, it doesn't.

I will spend the next bit of effort in the PMUFW code to try to disable PM even more...

If you have any new clue, please let me know!

Thanks in advance!
