I use the Blackbird motherboard and the Navi 10 GPU. It does not work with the Petitboot but it starts working after loading Fedora. The patch is located in the Kernel and therefore once I load Fedora and consequently the Kernel, the graphics card starts to work regularly. Using a patched kernel, the kernel works smoothly and gives me the ability to use Navi 10 on Fedora. They told me that from the Fedora 32 kernel, or from 5.6.6 onwards, the patch that we have used so far in the modified Kernels was already installed but it turned out that there was a bug when it was inserted and so it doesn't work. In fact, if I try to start one of the official Fedora 32 kernels, at the end of the load, the system remains stuck and never starts. He completes the loading of the operating system but then fails to start and remains on the loading screen without doing anything anymore, he has to reset and restart it. Is there a way to fix this bug and make the official kernel work with Navi 10 regularly? The information I have is this, I don't have anything else.
