Linux crash analysis - this is a subject that has lots of unanswered mail threads and plain text documents scattered all over the place, inaccessible to almost everyone, save the tiny percentage of super geeks.
My personal and professional interest in the last three years has taken me down the path of Linux kernel secrets, all the way into assembly code, where magic happens. I felt the desire to learn what happens in the heart of the system. Like most technical topics, there was some information to be found online, but it was cryptic, ambiguous, partial, nerdy, or just not there at all.
