We don't need any other info on the hwloc side. And we thank you for testing the big hwloc warning code :)
For HP: * 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.
