Cannot boot in Ventura: Panic diags file unavailable, the system auto reboots every time

[Apollo13]

Hello,
I need some kinda support because I cannot boot in Ventura and the system restarts every time. My hardware configuration is in the signature, but for more details, you can ask me.

The starting point:
I have currently a fully working hackintosh with Big Sur installed on my workstation along with OC 0.9.2. For a future upgrade to Monterey, I bought some days ago a Sapphire Nitro+ RX580 8GB and mounted in place of the previously running ASUS GTX 680.
Big Sur was working with the Nvidia GPU, it is working now with the AMD Rx580. This is the starting point.

The Ventura project:
The EFI working folder for Big Sur has been copied to a USB stick and then I applied the patch published at this GitHub (+ core count settings for my 12-Core AMD Ryzen): https://github.com/AMD-OSX/AMD_Vanilla
I haven't done many other changes to the EFI, because it is working on Big Sur, just to avoid new "variables" which could lead to issues.

macOS Ventura was installed on a separate SSD.

I boot from the USB stick and after some 10 or so seconds, the system auto-restart.
These are the very last log rows I was able to catch.



I googled the entire day that panic error (Panic diags file unavailable) but I could not find any useful information.

Has anyone already gotten this error?

Other details:
1) in my MoBo PCI-E slot 1 I have a Solarflare SFP+ card: it is not a factor, because I tried with and without it attached.
2) my GPU is installed on the PCI-E slot 2 (due to a massive water-cooling system I have): it is not a factor, because I even tried on the fly with the GPU in first slot.
3) Ethernet ports: I tried both with and without LAN cable plugged in.
4) ResetNVRAM, CleanNVRAM: tried both.

Honestly, I cannot know what else.

I really appreciate some help from you, who are very experienced and skilled people.

Thank you in advance.

@Apollo13 can you share a full image of the panic please?

I see smbios imac 19.1, change it.

Post a copy of your EFI folder so we can see exactly what you are using to boot your system.

Both recommendations above would be a good start.

The first because the error message containing the important kernel panic details occur/are shown before the section of the screen you posted above.

Second you should be using a SMBIOS for an Apple system that doesn't use or contain an IGPU, such as the iMacPro1,1 or MacPro7,1 SMBIOS. You should never use an iMac SMBIOS with an AMD system, as 99% of the time if an APU is present you need to disable it, and use a discrete GPU to run macOS.

Hello @Shaneee @Lorys89 and @Edhawk and thank you!
please find attached my EFI Folder.
As suggested, I modified the SMBIOS, from iMac19,1 to iMac1,1 but I got no luck with the results.
I'll try with MacPro7,1 and report only if a positive return.

How can I catch the full panic? Is there a way to store the verbose log output to text file?

Any reason you didn't post here? It's @CaseySJ configuration in some form or another...
