I quickly looked at the manual and noticed the 8548 has a different number of local access windows than the default 8. Please try to set law_max to 10 in ocpbus_probe(). Another thought: try not to instantiate LBC child (in ocpbus_attach() just comment out ocpbus_mk_child(dev, OCPBUS_DEVTYPE_LBC, 0)) and let me know if this changes anything. > Is it normal that "decrementer" frequency is 0 ? This isn't good, are you sure a proper value is given to decr_config()? Rafal
