2.4.24, ACPI, hyperthreading and strange messages

2.4.24, ACPI, hyperthreading and strange messages

[Dale Harris]

Howdie,

I'm seeing some usual messages from dmesg with a kernel that I have
running on a cluster.  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]

[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?

Just for completeness, below is the differences between my kernel and
2.4.24 vanilla:
