While attempting to load a Network extension with OSSystemExtensionRequest I keep getting a "didFailWithError error 1". SIP is disabled. Does anyone know what code 1 is and how to fix it?

Was wondering if we are getting any closer to seeing some PCIDriverKit Example code. Thank you.
Looking for some documentation on the Ethernet Bonding Driver. Working on a Ethernet kext driver that was working, but now when I create a bond, each link from this card/driver comes up a "invalid link". Would like to check the doc to see if the driver is doing something work. It was working in the past.
I have a driver that was written with IOKit. It works fine on BigSur with an Intel Processor. It is compiled as a universal binary. Each time I try to use kextload to load the kext, the machine crashes with the following....

last started kext is my kext, which makes sense.
Anyone seen this before and been successful in debugging it?
Thanks
Looking for Driverkit examples, I see a reference to this page.. https://developer.apple.com/documentation/networkingdriverkit/connecting_a_network_driver. However the page is not found. Any idea when this example will be available?
I am working on porting an existing KEXT to run on M1 on MacOS 11.2.3. It currently works fine on Intel Based Macs. I have the KEXT currently signed to "Run Locally". It loads OK on Intel. On my M1 MBP I adjust the Security Policy to allow the KEXT to load and also disabled SIP. When I attempt to load the KEXT the first time, I get the warning to allow it to load. I allow it and restart. Then after the reboot, I attempt to load the kext, it complains that "A program has updated system extension(s) signed by .... that will be incompatible with a future version of macOS, etc." I approve the load in the system preference and reboot. I then attempt to load the kext and I am presented with the same message. If I re-approve and reboot, the message comes up again. I am stuck in this loop. The following is the output of sqlite3…

I am working on getting this kext working as a stop-gap so I can get recreate the driver with DriverKit.
Any advice as to what I can do to get this kext loaded on the M1?
