Can you show your work here? There certainly must be ACPI information for such devices to be enumerated. Can you dump the ACPI tables relevant to the UARTs? _______________________________________________ driver-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/driver-discuss
