                    Known issue. Use 3.8.3 and higher with
                      qemu 1.4+. There's a known issue with qemu 1.3
                      with newer kernels (>3.7).

                      is 3.7.6-102.fc17.armv7l.

                I have now tried 3.8.3-102.fc17.armv7l and it still
                fails to boot. The last known good kernel is
                3.7.6-102.fc17.armv7l. 

              
        What's the command line you're using to
          boot it? Are you specifying a dtb file?

    The full script I use is below. Every time I test a new kernel, I
    copy vmlinuz, initrd, and the dtb directory. All of my tests were
    done with vexpress-v2p-ca9.dtb for each kernel.
