I have my patch in place to work around the problem and am looking into the the memory driver. In acpi_memory_enable_device in list_for_each_entry(info, &mem_device->res_list, list) { if printk ("node: %d , start %08lx, end %08lx \n",node,info- >start_addr,info->start_addr+info->length); before doing the add memory I see node: -1 , start 1f0000000, end 270000000 On node -1 totalpages: 0 node: -1 , start 170000000, end 1f0000000 Finding the 2 ranges (these are the right ranges and the right chunks) is great but acpi_get_node is not working for my handle. I am continuing to debug.
