I am running an AMD Athlon. I actually installed from the i686 ISO image. I unpacked the stage3 file and jumped in at 'Final steps".

I compiled the kernel (my first ever), accidently leaving it as i686. Can't remember if I compiled network support for my Realtek 8139 card as a module in "in-kernel". Anyway it booted and it ran, so I installed KDE3 and a couple of other things.

Today I decided to do another kernel build, this time for Athlon. I selected to have the 8139 support as a module. The compile appeared to run fine - or at least I think it did, the screen scrolls so fast who can tell. When I booted it the 8139too.o driver failed to load with an unresolved "_mmx_...." message.

Does the "_mmx_..." imply that it was looking to link to an Intel specific address point that was no long in my "Athlon" kernel? I got networking back by recompiling with direct 8139 support and am typing this message on the box.

Another question. When you build a kernel will it compile the driver modules as well ro do you have to do that specifically?

in /usr/src/linux do an
Code:

cp .config ..
make mrproper
mv ../.config .

before you start with make menuconfig etc. to get really rid of old stuff.

and yes, you have do build the modules (well not in any case /need/ to, but in any case useful ;) if you build a new kernel.

and don't forget to reemerge alsa-driver, nvidia-kernel, lm_sensors and/or any other package that builds kernel-modules that you have installed (if you don't have this stuff patched into the kernel, that is)


regards,
tom
