Test is quite simple: Build arm:collie_defconfig, run with qemu-system-arm -M collie -kernel arch/arm/boot/zImage --append "console=ttySA1" -monitor null -nographic Prior to the above commit, there is console output (the image crashes because it doesn't have a root file system, but that is irrelevant). After the commit, the console is silent. Let me know if I can do anything to help tracking down the problem.
