Created attachment 121914 [details] [review] fix-qemu-south-bridge-detection The driver misdetects PCH on your machine. Could you provide a log booting with drm.debug=14? Also the output of lspci -nv (booting with nomodeset)? Attached is a patch from -rc3 that fixes a similar issue, please give it a try. Closing it based on the IRC feedback: 11:12 < spstarr> thanks, -rc3+ fixes gen4.5 detection |
