Ingo, yup -- I put in a printk and commented out the set_dev_node() call when debugging this and got this output:
quirk_amd_nb_node: current numa_node = 0x0, would set to val & 7 = 0x0 quirk_amd_nb_node: current numa_node = 0x0, would set to val & 7 = 0x1 quirk_amd_nb_node: current numa_node = 0x0, would set to val & 7 = 0x2 quirk_amd_nb_node: current numa_node = 0x0, would set to val & 7 = 0x3
The issue appears to be that the HW has set val to a valid value, however, the system is only configured for a single node -- 0.
I realize that I'm working around broken HW ... but I think that a quirk, quirk_amd_nb_node(), should at least keep systems booting ...
