The symptom is hard to miss: the machine locks up at the spinner : just before printing the copyright message at the beginning of the boot : sequence. I've seen this on laptops that don't clear their RAM for a long time. I suspect that it is something different, however. My bug is that the kernel goes looking for dmesg buffer, finds a bogus pointer and walks off the edge of the world. Bang, you are dead.
