We don't need any other info on the hwloc side. And we thank you for
testing the big hwloc warning code :)
* If you're lucky, the BIOS may talk about the number of NUMA nodes
(either on the usual messages during boot, or in the BIOS configuration
menu). See if it says 2 on the broken node instead of 4 on other nodes,
you have something easy to tell HP.
* Otherwise we'll have to dig in the SRAT ACPI info. "dmesg | grep SRAT"
should talk about some "PXM" properties, which are basically NUMA
localities. You should see PXM 1 and 2 on the broken node, and PXM 0, 1,
2 and 3 on the other ones. SRAT comes from ACPI, if SRAT is broken, the
hardware/firmware is buggy.
