    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'
