Hi,
my apologies if this is an issue already solved:
I have no idea what these messages exactly say, but for reasons of symmetry I
think there's something wrong:
For a Sun Fire X4100 with two Dual_Core Operon processors, the kernel (SLES10
kernel (x86_64, 2.6.16.21-0.15-smp)) says during boot:
<6>SRAT: PXM 0 -> APIC 0 -> Node 0
<6>SRAT: PXM 0 -> APIC 1 -> Node 0
<6>SRAT: PXM 1 -> APIC 2 -> Node 1
<6>SRAT: PXM 1 -> APIC 3 -> Node 1
<6>SRAT: Node 0 PXM 0 100000-f4000000
<6>SRAT: Node 1 PXM 1 20c000000-40c000000
<6>SRAT: Node 0 PXM 0 100000-20c000000
<6>SRAT: Node 0 PXM 0 0-20c000000
[[ Note: "Node 0" is mentioned three times, but "Node 1" is only mentioned once.
If this is intended to be some address assignments, they look quite odd to me.
Does the following really mean that only one node can do DMA (the other has zero
DMA pages)? ]]
<6>ACPI: SLIT table looks invalid. Not used.
<7>NUMA: Using 26 for the hash shift.
<6>Bootmem setup node 0 0000000000000000-000000020c000000
