Kernel compilation <ERROR: "pm_idle" [arch/x86/kernel/apm.ko] undefined!>

Hi, guys. I tried to compile linux kernel in Ubuntu according to this tutorial.
But after 2 hours of compilation process I get this:

I found solution.
In make menuconfig I switch off "APM" module.
And compile kernel according to this tutorial.
