Summary: kernel memory corruption

Initial Comment:
The console output gets partly clobbered when is start an Ubuntu 8.10 (amd64) guest.

commit dbfc099daa953a41a3572a7b8d72f75cc23604f1

introduced that behavior.

The problem goes away when I revert the changes to qemu/cpu-all.h and qemu/exec.c (see patch)

Message:
You can also easily reproduce the bug using:

ftp://releases.ubuntu.com/releases/hardy/ubuntu-8.04.1-server-amd64.iso

# qemu-img create -f qcow2 test.img 4G
# kvm -hda test.img -cdrom
/var/lib/vz/template/iso/ubuntu-8.04.1-server-amd64.iso -m 512 -net nic
-net tap

After the first boot you get various error and you can see the partly
clobbered console (latest kvm-83)
