igpu kernel panic

[invictus]

Hi guys,

who can help me investigate this kernel panic? It's been too long trying to fix this. I need help.

System: Fujitsu G558 - micropc with DP and HDMI(1.4) based on H310 chipset. CPU i3-9100 with UHD630 (dev-id 0x3e91). UEFI boot only. No legacy boot in BIOS as an option. I have tried all memory fixes, all Hackintool guides and presets.

Catalina - 10.15.3

Thank you!

the problem is framebuffer

u have a full video patch?

[invictus]

Hi,

 

I did the simple patch. Then the stolen memory patch. All framebuffer patching guide. I don't know my connector data. But the question is this: why I not boot to OS with the patch? I should boot to OS without acceleration. Instead I get kernel panic.
