Re: How to debug a hang while booting the kernel?

That is not a panic. It is a hang and I need some detailed information

FWIW, when I had to isolate an interrupt stack overflow with Xen, in
order to find where it fails, I put a break on the last printf I saw on
screen, then used "step <count>" until I managed to find the approximate
part in code where it stalls/crashes, then added a couple of printfs to
see what happens there, eventually helped with some generic ddb commands.
Worked to isolate an issue inside pckbc with Xen.
I know, this sounds like a dirty hack :)
