 Hi Paul,

 By starting QEMU with the following command:

~/bin/qemu/bin/qemu -hda root_fs-qemu -kernel bzImage -append "root=/dev/sda console=ttyS0,115200 console=tty 4" -monitor telnet:localhost:4555,server -snapshot

 And the running telnet on another terminal:

~/ telnet localhost 4555

 I get 100% of CPU for a while and the following assertion is trigged:

qemu: /home/lcapitulino/src/qemu-qmp/hw/qdev.c:194: find_prop: Assertion `prop->type == type' failed.

 It works if I revert 1431b6a17e6546569e09bcf8fb7773c925658d8f. Stack
backtrace follows (although I'm not sure whether it's needed/helps):
