I tend to bounce back and forth between Linus' -pre patches and your -ac patches. For instance, when 2.4.4-ac4 came out, I was running 2.4.5-pre1. Here's what I did: zcat patch-2.4.5-pre1.gz | patch -p1 -s -E -R zcat patch-2.4.4-ac4.gz | patch -p1 -s -E mv .config .. make mrproper mv ../.config . make oldconfig make dep && make bzlilo modules modules_install I apply nearly every patch set that comes along from you or Linus, and this is the way I usually do it. Every once in a while, I run through all the options in menuconfig just to make certain nothing has gotten hosed up. Only once can I remember needing to change an option that had been set incorrectly by oldconfig. Wayne
