Hi Fabiosun, I hope you're doing well. I've followed your X870E Hero thread for some time, and it inspired me to build a similar system. I finally have it assembled and tried to install Sequoia, but I'm stuck at the AHCI initialization point. My System Build: CPU: AMD Ryzen 9950X Motherboard: ASUS ROG Crosshair X870E Hero BIOS: 1715 RAM: GSkill 96GB (2×48GB) Storage: Crucial T705 NVMe (PCIe 5.0) GPU: AMD Radeon Pro W6600 (workstation) Using the OpenCore EFI you mentioned works for you and prepared for viljeml (BIOS 1715) The Issue: The system hangs at "Successfully initialized AHCI controller" during Sequoia boot and becomes completely unresponsive. What I've Tried: Removed RX 6950 XT GPU properties Tested with/without agdpmod=pikera Tried npci boot arguments (0x2000, 0x3000) Tested different USB ports, EFI versions, and minimal kext configurations, but every test results in the same hang point My Question: do you think the issue is that I'm using a W6600 Pro workstation instead of a GPU like your 6950 XT? Would switching to a consumer RDNA2 card likely resolve this? If you have any insight, I would really appreciate it. Thank you, Steven
