Tested with kernels 2.4.5-RH through 2.4.13-ac7. With Bios image v1.12 it hangs with agpgart built in or on module load exactly as you described, it also fails when I use nvidia's NVdriver agp support. After upgrading to Bios 1.13 the problem went away. Something to check for anyway... For completeness, my working setup displays the normal kernel apggart info and shows this: 00:01.0 PCI bridge: Intel Corporation 440BX/ZX - 82443BX/ZX AGP bridge (rev 03) (prog-if 00 [Normal decode]) Flags: bus master, 66Mhz, medium devsel, latency 64 Bus: primary=00, secondary=01, subordinate=01, sec-latency=64 I/O behind bridge: 0000d000-0000dfff Memory behind bridge: fc600000-fe6fffff Prefetchable memory behind bridge: f0400000-f44fffff Regards, Reid - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
