I'm not sure why yet, but commit 8a97c432 ("KVM: PPC: booke: Improve timer register emulation") in Alex's kvm-ppc-next branch is breaking Book3S HV KVM on POWER7. Guest cpus fail to spin up, and even with just one cpu, the guest stalls every so often. If I stop the guest and inspect the state with qemu, PC is at 0x900. Reverting 8a97c432 makes it work properly again.
