Ofcourse there's an init on the busybox-rootfs, and I'm able to boot it with an x86_64 Linux. The reason for panic is incorrect: I think (although not sure) a 32-bit rootfs userland will work. >> [1] 25526 abort (core dumped) linux ubd0=busybox-rootfs >> % >> >> Rubbish. > > UML core dumps at panic() by design. On a related note, why does it screw up my terminal?

Wrong. $ make defconfig ARCH=um SUBARCH=i386 *** Default configuration is based on 'i386_defconfig' # # configuration written to .config # I can build a 32-bit kernel just fine with my patch applied. -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
