Hello, on my dell lns7590 I found that "division-by-zero" caused the kernel to crash. The division-by-zero "WhateverGreen driver does not seem to solve this problem.
This is my problem report
Code:

You'll need to use Clover and use the correct dpcd-max-link-rate values in Clover/Devices/Properties within your iGPU. I tried this with OpenCore recently but could never get it to work correctly. There may be different values or a process for OpenCore.
