So I've tried to get DRM working again, both with your original patch (modifying the drm code to use kmem_alloc), and with a modification to kern_malloc to return page aligned memory for allocations >=NBPG. Both ways could work. I'm running into another problem now: KVM shortage or fragmentation. The agp code tries a bus_dmamem_map() which calls uvm_km_alloc(..., UVM_KMF_VAONLY) The size is about 40MB. This request fails, and the X server doesn't start. Any ideas how to reduce KVA usage? best regards Matthias ------------------------------------------------------------------------------- ------------------------------------------------------------------------------- Forschungszentrum Juelich GmbH 52425 Juelich Sitz der Gesellschaft: Juelich Eingetragen im Handelsregister des Amtsgerichts Dueren Nr.
