Greg, A quick test would be to revert the following patch (assuming you are using a BeagleBone variant) in your tree, if you continue to use your old firmware https://github.com/beagleboard/linux/commit/620cab817e7a06065452d4c119c3066061ad5f03

I am going to continue to experiment with the old and new PRU package and see if I can determine the problem. I think I need to look at the device tree I am using and see if it has the required properties.

It provides the irqchip/irqdomain which will allow client users to use standard DT properties for listing the PRU system events as interrupts and use standard Linux APIs. There is still some more work to be done there (ability to add system event to PRU channel mapping to host interrupt from DT) rather than having to provide that mapping data in firmware resource table, so the MPU-side clients can be cleanly separated and depend on Linux infrastructure alone. I am not sure how much the kernel you are using has caught up to the changes I have been doing on my tree, but there are a few changes over the last week where we added and switched over to PRU system events instead of mailboxes for scalability purposes (mailboxes would work too provided you choose mailboxes in DT over interrupts). This is what Jason was referring to as v5.0.0.
