Hi Oliver, SIS 655 does also require the delay workaround not to freeze. Following, the relevant kernel log of my machine (SIS655TX with Radeon 9200): cdj:~# dmesg |grep -i agp Linux agpgart interface v0.100 (c) Dave Jones agpgart: Detected SiS 655 chipset agpgart: Maximum main memory to use for agp memory: 941M agpgart: AGP aperture is 256M @ 0xe0000000 agpgart: Found an AGP 3.5 compliant device at 0000:00:00.0. agpgart: Putting AGP V3 device at 0000:00:00.0 into 4x mode agpgart: SiS delay workaround: giving bridge time to recover. agpgart: Putting AGP V3 device at 0000:01:00.0 into 4x mode Cheers, Cédric Rivard
