On an Asus KV8-S XE motherboard, the agpgart module is unable to properly determine the AGP aperture size, regardless of bios options (AGP 8x mode & AGP 4x mode), this *might* also be related to possible hangs in X11 when using DRI. Bug was seen on the following config: Asus K8V-S XE motherboard, 512MB ram with AMD Sempron 3200 (Athlon64 core) Witnessed with an ATI Radeon 9700 Pro card and with an Asus Radeon 9200 SE. I'll try & test this config with some more gfx cards to see if the gfx card has any influence on the detection, but i'm not sure i have any nVidia cards available. This phenomenon has been found in atleast the following kernel versions: linux 2.6.12-r9 linux 2.6.14-r4 linux 2.6.14-r5 linux 2.6.14-r7 The reported aperture size is always 32M, more details can be provided, just ask what you need to know. With kind regards, Ochal Christophe
