hi,so i recompiled kernel without IOMMU and selected CONFIG_AGP and CONFIG_AGP_AMD64 to be compiled as modules
What does dmesg say about agp?
now i get Linux agpgart interface v0.101 (c) Dave Jones agpgart: Detected AGP bridge 0 agpgart: AGP aperture is 128M @ 0xc80000000 agpgart and amd64_agp modules are loaded automatically however, neither drm nor radeon modules can be loaded. drm still reports Error inserting drm: Cannot allocate memory and radeon isn't being loaded because of the reported missing drm_* symbols.i'll probably try to recompile kernel one more time to be sure that with IOMMU the AGP is not recognized and reported by the kernel...
