Hi,
I suffered from similar problems caused by a JMicron JMB582 controller
put into a RockPro64. It did not manage to properly deliver interrupts
over msi. Forcing it to intx solved the problem for me. After adding a
workaround to the driver I sent the sata card to kettenis@, so that he
can try it on a different board. Your dmesg doesn't identify the ahci
chipset and interrupt mode.
This is what I did:

maybe something similar will help your controller deliver interrupts?
