I'm unable to reproduce.

Can you provide the stack trace where this hangs? Add
CONFIG_DEBUG_INFO, and then

- copy vmlinux somewhere on the host filesystem
- start the guest
- when it hangs, type 'gdbserver' in the qemu monitor
- on the host, the 'gdb /path/to/vmlinux'
- 'target remote :1234'
- 'backtrace'
