Now, the question is: Why? What has changed between 4.16 and 4.17 that makes this necessary? And, is it a bug or a feature? To finally get back to you about this "windfarm" business I can tell you that an out-of-the-box build of the latest stable kernel results in all the expected

Why would I want to through out working computers and replace them with new ones, just because the new ones happen to be little endian? I have no such desire. I have ppc64 and arm7 boxes laying about for experimental reasons as well as educational reasons. Dennis

Again, too much ranting. If you think all is lost and putting efforts in Debian Ports is pointless, you're in the wrong forum. Efforts in debian ports isn't pointless. One should make a distinction between working with a platform with a future and a platform from the past. Dennis

Make sure you build initrd with MODULES=dep and not "all" modules via /etc/initramfs-tools/conf.d/* or in /etc/initramfs-tools/initramfs.conf as well CONFIG_DEBUG_INFO=n in kernel config. I usually trim down the config to the minimal and then merely throw "make modules_install" after
