FWIW, there is a PowerMac image in arch/powerpc/boot called "zImage.pmac", so why not use that one instead? > Starting with the kernel source linux-source-5.14.tar.xz installed from > "apt-get install linux-source", > > Test 1) Compile using config-5.14.0-2 > X fails as before; everything else seems to work.
