Thanks for the report, did you bisect the mmotm series to identify the root cause? What does your .config look like? I tried kvm with the patches (mmotm 30th July) and qemu-kvm (30th-july) with a Fedora 11 guest image and the system booted just fine for me.
Could you share your command line as well?
