I have an iBook G4 and some older Apple Powerbooks somewhere in my basement. > I also have an iBook G4 which I refrained from updateing until now. > I could, by holding the current kernel, just for safety :) Installing the updated kernel does not remove the old kernel. You will be able to choose the preferred kernel in the GRUB menu. >>> What is this regulatory.db? what firmware could I miss? >> That's just for WiFi, unrelated to your keyboard. > > Ok! wifi works... but always at my second attempt to pull it up :) It will work with or without the database. It might just not be legal without the database. To fix this problem, install the wireless-db package: > https://packages.debian.org/sid/wireless-regdb > The keyboard works in GRUB and works with a previous version of the kernel.... > what else can I test and say?

Just build a normal upstream kernel with the config you created using make localmodconfig on the laptop itself. > I can also attempt a native compile I don't know how to build & package a > kernel > so that it is digested by debian You don't need to build a Debian kernel. Just checkout the kernel from git on a fast machine, copy the .config file over from the laptop generated with "make localmodconfig" and start bisecting between v5.8.0 and v5.9.0. # apt install gcc-powerpc-linux-gnu (as root) # export ARCH=powerpc # export CROSS_COMPILE=powerpc-linux-gnu- # git bisect start # git bisect good v5.8.0 # git bisect bad v5.9.0 # make -j<number of cores) # make modules_install INSTALL_MODPATH=/path/to/modules Then copy over the kernel and the modules from INSTALL_MODPATH to test. Mark a working kernel with "git bisect good", a bad one with "git bisect bad". Repeat until you find what broke the keyboard. Adrian -- .''`.
