Hi again

You're a very patient human!

I have attached the verbose image, and the current EFI folder.

Here are the differences between my working Mojave and the troublesome Catalina:

---------Mojave boot (current setup):
drivers/uefi/
ApfsDriverLoader.efi
EmuVariableUefi.efi
FSInject.efi
HFSPlus.efi
OsxAptioFix2Drv-64.efi
SMCHelper.efi

kexts/other/
AppleALC.kext
FakeSMC_ACPISensors.kext
FakeSMC_CPUSensors.kext
FakeSMC_GPUSensors.kext
FakeSMC_LPCSensors.kext
FakeSMC.kext
IntelMausiEthernet.kext
Lilu.kext
USBPorts.kext
WhateverGreen.kext

acpi patched:
(empty)

config
Arguments = "dart=0 shikigva=16";


________________________________________________________________________

==========Catalina
drivers/uefi
ApfsDriverLoader.efi
AppleGenericInput.efi
AppleUiSupport.efi
FwRuntimeServices.efi
HFSPlus.efi
OcQuirks-4.efi
VirtualSmc.efi

kexts
AppleALC.kext
IntelMausiEthernet.kext
Lilu.kext
SATA-200-series-unsupported.kext
SMCProcessor.kext
SMCSuperIO.kext
USBPorts.kext
VirtualSMC.kext
VoodooPS2Controller.kext
WhateverGreen.kext

acpi patched:
SSDT-EC-USBX.aml
SSDT-Z390-RP05-SLOT4-TB3HP.aml

config:
Arguments = "-alcbeta -lilubetaall debug=0x100 keepsyms=1 -wegbeta -no_compat_check slide=0 -vsmcbeta";

device properties: removed

Delete the SSDT-Z390-RP05-SLOT4-TB3HP.aml file.
Put back the SSDT-PMC.aml.

Delete the SMCProcessor.kext.
Delete the SMCSuperIO.kext.

I'll have a go at it. (I did delete the SMCSuperIO.kext, and try again, but that fatal error still showed up. That really confuses me, but perhaps the changes you suggest will work to cure that mystery...)

Back in a few...

 

[kentval]

OK... now it's even more interesting.

I noticed that the fatal SuperIO error was associated with the nvme, so I went into my BIOS and disabled the nvme (took it out of the boot loop). Lo and behold, the verbose scroll suddenly went on for Many more lines.
It finally stopped with two lines I had to video in order to see them before they disappeared.
Attached is a screenshot of that video. A 10th of a second after the last line appeared, the screen went black, and the show was over.

That's a graphics error.

Open the config.plist.
Go to Devices > Properties.
Delete every PciRoot device.

I forgot to delete those when I posted them and it's configured for my Radeon VII...

 

[kentval]

Thanks, but that was mentioned somewhere. In the current config.plist there are no Properties at all.

Ran it all again after changing an ATI inject = yes to inject = no. Again took Nvme out of the boot loop. I got about a thousand USB errors before it finally quit to the black screen. See attached. The ground keeps changing under my feet! ;-)

You are still getting a graphics error. I don't know why... Vega 64 is supported and you have WhateverGreen installed...

 

[kentval]

I took out my USB.kext, to see if that had any effect, but the zillions of USB errors continued unaffected.

I'm also a bit concerned about the "fatal" issues when the Catalina boot process hits a Nvme ssd. Those are my main drives, boot and work. (Mojave works fine with the Nvme's.) If I can't boot with them installed, Catalina will be history for me. I only recently bought this hardware, and can't afford to replace it.

Well, at least the issues are "not trivial." Keeps things interesting, eh? Do you know anyone here who has a Z390

Thanks again for your courtesy.

I have a Z390 and it's been working very well since I got the NVRAM working.

I'm pretty sure that once you get past the graphics error, you will be fine.

 

[kentval]

Excellent, that you have a 390.

one thought: the boot arguments. My Mojave boot arguments are just for the Vega:
dart=0 shikigva=16

You provided boot arguments are:
-alcbeta -lilubetaall debug=0x100 keepsyms=1 -wegbeta -no_compat_check slide=0 -vsmcbeta

I have not got a clue what that's all about.

Should I try swapping them out (or is there something in that Greek-to-me string)
