Why wasn't it booted in real machine?

Thank you for the detailed information about your build environment.
Could you describe more precisely the error which occurs? Do you see any output (e.g. "iPXE initialising devices...")? At what point does the machine reboot?
Thanks,
Michael

I was writing debugging code. The Debugging process was recorded to the youtube video.

[Problem Call Stack]
main() => initialise() => initialise() return !! => startup() => core/devices.c : probe_devices() => PCI probe call => pcibus_probe() => ath9k_init_device() => ath_rx_init() => ath_rxbuf_alloc() => infinite reboot
I think it was being happened in ar9xxx code.
Thanks for assistance!

Thanks for tracking that down. ath_rxbuf_alloc() was very broken. I've pushed a change to fix this one small part of the driver: http://git.ipxe.org/ipxe.git/commitdiff/d0bfd83.
If we find any more bugs of this magnitude, then I'll just remove the whole ath9k driver.

iPXE is compiled.
Thanks for your answer.
