Hi Jalus, > This is where I'm confused; which .config file (/proc/config.gz or > /boot/config)
The two should have the same content most of the time. You can use either. config.gz needs to be decompressed (e.g. with zcat). > where in the kernel source tree do I put this file in. In the root of the kernel source tree which is /usr/src/linux if the new kernel is set with eselect kernel. Make sure to read https://wiki.gentoo.org/wiki/Kernel/Upgrade which explains all these steps in detail. --- Andrew
