Yes, it looks like that. The ordering now seems to be id 9, 10, ... 14, 0, 1, 2, instead of the default of id 0, 1, 2 ... Did you expect a change in probe ordering ? When I switch back to the old AIC driver the ordering goes back to default. Regards Suparna > > James > > -- Suparna Bhattacharya (suparna@in.ibm.com) Linux Technology Center IBM Software Lab, India
