I have hyperthreading capable Xeons, Supermicro mobos, and the nodes have LinuxBIOS (but the mayor does not). I had to bump the CONFIG_NR_CPUS to 8 to be able to even see both CPUs on the nodes. The messages I see that concern me are: [on the nodes, where hyperthreading is not activated]: WARNING: No sibling found for CPU 0. WARNING: No sibling found for CPU 1. [next occurs on the nodes and the mayor] ACPI: System description tables not found ACPI-0084: *** Error: acpi_load_tables: Could not get RSDP, AE_NOT_FOUND ACPI-0134: *** Error: acpi_load_tables: Could not load tables: AE_NOT_FOUND ACPI: Unable to load the System Description Tables PCI: Probing PCI hardware PCI: ACPI tables contain no PCI IRQ routing entries So the problem occured independant of what BIOS I have, at least so it seems. Links full kernel config and dmesgs are below: [a node, with linux bios, no HT] http://research.amnh.org/users/rodmur/dmesg.new [the mayor, no linux bios, HT activated] http://research.amnh.org/users/rodmur/dmesg.dmtr [kernel config used on all machines] http://research.amnh.org/users/rodmur/config.bproc Is there a problem with the kernel or my configuration of it? -- Dale Harris rodmur@maybe.org /.-)
