Hi all,
I just tested to compile linux-2.5.45 with this xtreme minimal .config (also attached)
Basically I turned off everything that was "off-able" (not sure it this word exists ;))
using "make menuconfig".

Note: This configuration might produce "not so useful" kernel,
but that's how I tested the kernel configuration.
I got the following error:
