Non CS-major here (in fact I did math). I don't know anything about kernels or micro-kernels. Easy cases, even grossly over-simplified cases would be relevant.

I know that every time I run a command into bash Linux is doing all sorts of fancy memory-allocation and queueing and more. All the books I am finding are either way too technical or grossly out of date.

Here is a cute course on Compilers: http://web.stanford.edu/class/cs143/

Actually they are not that out of date... Tanenbaum's Operating Systems and Computer Networks are both good. The BSD book by McKusick is excellent for more advanced students. For example, they don't cover SMP much, but locking and queuing, so you are prepared for studying SMP.
