Also we need to look for alternatives. There is a chance
to create crashdump and get the ftrace messages from it.
Also this might be scenario when we might need to suggest
the early_printk() patchset from Peter Zijlstra.  

I'd be happy to repost those. I still carry them in my tree.  

You do not need to if they are still the same as

I rather do not promise anything but I would like to look at them
within next few weeks (after the merge window).  

Sure, I'll post them again during/after the merge window.

BTW, this is what I ended up using to get the debug information I
