I tried other board. The K8+rs690+sb600 and k8+rs780+sb700 don't work on current version, while fam10+rs780+sb700 works. I doubt that it has something to do the spurious interrupt or timer interrupt. I don't know. Do you have any idea?

This will break quite some other boards... Is there any particular reason why the dbm690t will not work in virtual wire mode? I think either the sb600 code should call clear_ioapic() instead of setup_ioapic() or (maybe better) the setup_ioapic() function should get an additional parameter virtual_wire Anyways, maybe we should try to unify clear_ioapic and setup_ioapic (also, the function should create a device node and append it to the bridge it is called from) Stefan -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
