--- Comment #8 from mypersonalmailb...@mail.com --- (In reply to comment #7) Hi Robert, Yes, I do understand the "reputation" of VIA Technologies chipset with AGP from 1998 to around 2002 or so. I remember that ALi was probably even worse at the time (i.e., ALi Alladin V chipset for Socket 7). Yet, to my surprise, almost all AGP graphics cards I tried were able to at least boot Ubuntu with Apollo MVP3 chipset. Since this NVIDIA RIVA TNT2 64 AGP graphics card from VisionTek does work fine with other systems, including newer VIA Technologies chipsets, I suspect there might be something wrong inside agpgart-via module specifically that causes issues with Apollo MVP3 chipset. I will try to obtain kern.log from this system so that someone can analyze it further.
