That's not cool - as I said before, I can't reproduce this behavior here
which means that the problem might be chipset-related. What you could do
now is to boot the kernel with "debug initcall_debug log_buf_len=10M"
and try to capture the whole boot log with a serial console - or if that
doesn't work - make a screenshot with a camera of some sort. This might
shed some light on the question where exactly your machine hangs.
