Hi,
I'm currently seeing a memory problem on a NUMA-enabled dual-Opteron 250 box with the 2.6.12.5 and 2.6.13-rc* (up to 7) kernels. Namely, the box has 12 GB of RAM, 8 GB of which is installed on the first node. The whole memory is detected but then only the first 8 GB of it is made available (minus some hardware-related holes), as though the memory on the second node were discarded for some reason.
I have observed that the latest Fedora Core 3 kernel (based on 2.6.12) is also affected by this issue, but the "out-of-the-box" FC3 kernel, based on 2.6.9, is not.
The motherboard is a Tyan S2882-D with the out-of-the-box BIOS, which is not the latest one. Should I upgrade it?
