Cannot start sequoia with ryzen

[ashcliffe]

I had a working hackintosh with i7 7700 and Z270. Had to upgrade my machine to Ryzen 7 5700X
I went through several iterations of configuration with the same result. I cannot get past [EB|#LOG:EXITBS:START]
There is no clear indication of failure.
Has anyone resolved this or at least figured out the reason?
Any suggestions are appreciated
Here is my config and the latest log from OC

The AMD Kernel Patches in your config.plist aren't the latest and they aren't set for Sequoia to boot. They are set for running Sonoma, i.e. MaxKernel 23.99.99. This should be MaxKernel 24.99.99 when booting Sequoia.

Download and install the latest version of the AMD kernel patches and edit the first four patches to match your 8-core CPU.

Just remember that Sequoia is the last version of macOS that supports the iMacPro1,1 SMBIOS. If you ever plan to move to Tahoe, then you will need to use the MacPro7,1 SMBIOS.
