Bug#551259: linux-image-2.6.30-2-amd64: fails to detect NUMA on Dell T7500
I see the same NUMA problem on updated Fedora 10 and 11 kernels, on Dell
T5500 and T7500. I also see the tbutils warnings about ACPI checksum
errors for TCPA and SLIC tables.
If Dell claims it is a Linux problem, it would help to know if they
claim that the SRAT and/or SLIT tables are actually defined. Is it
possible to use run-time notification via ACPI _PXM, and not have these
static tables? Does Linux support _PXM NUMA notification?
I tried toggling BIOS settings, like hyper-threading and virtualization
support, but these had no effect. It might help to boot with ACPI
debugging enabled, but Fedora kernels have that feature disabled.
