And it boots with numa=off ?

Try reboot=bios or reboot=triple

The original UnitedLinux install didn't default to NUMA, unless
you installed the special k_numa kernel. Later SPs did.
If you used an NUMA kernel can you please check which kernel

I'm a bit suspicious of this compiler. Any chance you could try it with a gcc 3.2 too?

The boot output for the NUMA scanning looks ok, I cannot see what's wrong with it.
