That's really strange. I use kvm (frequently updated to the latest git) daily and I don't face any such issues. Can you try this: Don't load the kvm modules (or rmmod kvm-amd; rmmod kvm if they're already loaded) and then try the qemu command line without --no-kvm? Does it lock up even then? Also, can you try what you've tried previously on a text console (not within X). If there's any kernel output, it'll be dumped.
