Description of problem: I can boot 3.11.0-0.rc3.git1.1.fc20 with qemu-system-arm but not 3.11.0-0.rc3.git4.1.fc20 or 3.11.0-0.rc4.git0.1.fc20. I get not kernel messages at all, qemu just spins.
Perhaps related, I cannot boot 3.11.0-0.rc3.git1.1.fc20 with -smp 4 either.
I'm guessing this got resolved with 3.11.0-3, but is now broken because of 3.11.0-300. The 3.11.0-300 issue is being tracked with 1007911. This isn't technically a duplicate, but I'm going to close it out now.
