Perhaps set up kdump?
It did not work on the default Debian. I suspect kdump got confused of 64bit kernel and 32bit userspace.
Smallprint: our maybe setup mtdoops. Finally a use for the flash.
Thanks for the suggestion, hopefully it will be helpful to other people in the thread. Or to me after I get some basic knowledge - while I'm pretty well versed in C/C++, I've never done any kernel or embedded development, so currently those words sound like some black magic incantations to me :-D
What do you want to achieve with your console cable?
You know process cores and how to debug them post mortem. kdump saves the kernel core of a crashing kernel. You can also debug it post-mortem on your next boot.
I use it all the time (not on the Pinbook Pro, though). Google for it
