Hi, guys. I tried to compile linux kernel in Ubuntu according to this tutorial. But after 2 hours of compilation process I get this: Code: UNROLL lib/raid6/altivec4.c UNROLL lib/raid6/altivec4.c CC [M] lib/raid6/altivec4.o UNROLL lib/raid6/altivec8.c CC [M] lib/raid6/altivec8.o CC [M] lib/raid6/mmx.o CC [M] lib/raid6/sse1.o CC [M] lib/raid6/sse2.o LD [M] lib/raid6/raid6_pq.o CC [M] lib/reed_solomon/reed_solomon.o CC [M] lib/zlib_deflate/deflate.o CC [M] lib/zlib_deflate/deftree.o CC [M] lib/zlib_deflate/deflate_syms.o LD [M] lib/zlib_deflate/zlib_deflate.o Building modules, stage 2.

What does it mean? What can I do?

I found solution. In make menuconfig I switch off "APM" module. And compile kernel according to this tutorial. https://wiki.ubuntu.com/KernelTeam/GitKernelBuild
