ACPI reports 'node -1' in dmesg on RHEL 5 and RHEL 6

Solution Verified - Updated -

Issue

References to a seemingly invalid "node -1" NUMA node may appear in dmesg. An example follows:

pci 0000:00:1e.0:   bridge window [mem pref disabled]
  alloc irq_desc for 28 on node -1
  alloc kstat_irqs on node -1
alloc irq_2_iommu on node -1
pci 0000:00:01.0: PCI INT A -> GSI 28 (level, low) -> IRQ 28
pci 0000:00:01.0: setting latency timer to 64
  alloc irq_desc for 29 on node -1
  alloc kstat_irqs on node -1
alloc irq_2_iommu on node -1
