As explained in the thread subject, kernel-3.7.3-101.fc17.armv7l.rpm provides a vmlinuz and initramfs that fail to boot under qemu. The previous version, kernel-3.5.6-1.fc17.armv5tel, does boot under qemu. From comments in the thread, I concluded that 
3.7.3 needs a device tree file (dtb) that is not being provided by the rpm, as an additional parameter to qemu (-dtb neededfile.dtb). I am using -M vexpress-a9, so the machine model is supposedly fine.
