Latest -git qemu-kvm doesn't boot an x86 kernel

[Aneesh Kumar K.V]

Hi,

I am trying qemu-system-x86_64 on a x86 host running 2.6.30-2 (debian testing)
kernel and trying to boot latest linus git kernel (x86). The kernel hang
after printing the below 

[   4.394392] ACPI: PCI Interrupt Link [LNKC] enabled at IRQ 11
[    4.397837] virtio-pci 0000:00:03.0: PCI INT A -> Link[LNKC] -> GSI 11 (level, high) -> IRQ 11
[    4.436489] ACPI: PCI Interrupt Link [LNKD] enabled at IRQ 10
[    4.439829] virtio-pci 0000:00:04.0: PCI INT A -> Link[LNKD] -> GSI 10 (level, high) -> IRQ 10
[    4.462538]  vda:
[    4.526913] input: ImExPS/2 Generic Explorer Mouse as /devices/platform/i8042/serio1/input/input3
[    5.349554] async/1 used greatest stack depth: 5872 bytes left


An earlier version of kvm booted fine the new kernel. So the vm disk image user space should
all be fine. The older version of kvm that worked fine is 
QEMU PC emulator version 0.10.50 (kvm-devel)


Any patches i need to try ?

Please try qemu-kvm.git (should be fixed by commit
1536fc28ae1954e2990c3ee14b4a92624ecfcb68).
