https://bugzilla.kernel.org/show_bug.cgi?id=216095 --- Comment #15 from Michal Suchánek (msucha...@suse.de) --- You do have two outputs defined in the device tree: /pci@f000/ATY,AlteracParent@10/ATY,Alterac_A@0 /pci@f000/ATY,AlteracParent@10/ATY,Alterac_B@1 If they correspond to a physical outputs is another question. After all if one of the outputs exists only on some card models it would never detect a connected screen on the cards on which the output does not physically exist and everything will work just fine. Here is a patch that aims to resolve the problem https://lore.kernel.org/lkml/20230117165804.18036-1-msucha...@suse.de/ -- You may reply to this email to add a comment.

Ok. To rule out influence of other drivers I disabled them (# CONFIG_FB is not set, # CONFIG_DRM_RADEON is not set) and only set CONFIG_DRM=y, CONFIG_DRM_OFDRM=y but it made no difference.

So you really do have two outputs but the problem is likely different: The hardware-specific driver gets initialized earlier, and then the offb/ofdrm driver cannot get the resources for the framebuffer because the native driver is already using them.
