I've seen this performance issue on my Tyan test rig; s2912 mainboard, mcp55 southbridge and 83xx Opterons. From the code in the serengeti_cheetah_fam10 target I'd expect the same behavior to manifest there. -- Arne. -- coreboot mailing list: coreboot@coreboot.org http://www.coreboot.org/mailman/listinfo/coreboot
