I'm assuming with this you mean

CONFIG_MK7, i.e. "Athlon/Duron/K7" in "Processor Family" under
"Processor Type and Features" in the kernel configurator? At least it
looks like this from your other mail with the failing .config.

Right, can you try this with the upstream kernel, i.e.

1. get one from
2. copy the .config into the directory where you've unpacked the sources
3. do 'make oldconfig' and then 'make menuconfig' and go and select Athlon build
4. do 'make -j3 > w.log 2>&1' so that you can catch the build output into w.log
which you can send later

Also, which build tools are you using, simply do


in the kernel source directory, catch the output and send it on pls.

This should be all for now, thanks.
