Not very Linux specific but Tanenbaum's "Modern Operating Systems" is an excellent source for OS theory and very readable as well. It's an expensive book, but I found it worth its money.
Seconded. I would add "Structured Computer Organization", as a preamble book. I read both as if they were novels - they really are interesting and written in such a way that can hook you just as a good story
I agree! I took Andy's class that he wrote the book for and it was one of the most influential classes I have ever taken. It is also one of the few books I have kept over the years and throughout all my travels.
