A question was posted by Mason in the comments section of How to compile a Ubuntu Maverick 2.6.35 kernel for Lucid

When I enable * Support for big SMP systems with more than 8 CPUs and Maximum number of CPUs . It will compile fail. I have try many times.

Any one know how to fix this problem ? Thanks

What error message do you get when compiling?

From what i can determine from sources online this might actually be a bug in the kernel. There are reports of other functions that show the same problem and it was related to 32bit.

You might want to bring this up on the kernel mail list.

Hi there,

setting CONFIG_NODES_SHIFT to a lower value than the default chosen by Ubuntu it compiles without complaining.

Cheers,
