[hitmoon]

Peter:

first launch following command:

arm-softmmu/qemu-system-arm -M versatilepb -kernel 
~/Qemu-ARM/vmlinuz-3.2.0-4-versatile -initrd 
~/Qemu-ARM/initrd.img-3.2.0-4-versatile  -hda 
~/debian_wheezy_armel_standard.qcow2 -append 'root=/dev/sda1'

Then execute 'info qtree' in the monitor, qemu aborted with error message :
'qemu/hw/core/sysbus.c:277:sysbus_dev_print: Object 0x55569a7b2d00 is 
not an instance of type sys-bus-device'

With the help of git bisect, commit 'hw/sd/sd.c: QOMify' 
(260bc9d8aa887bdd72d1b2499a9080f75b289cb4) cause this problem.
