Learning assembly for some machine, and writing a non-trivial program, or writing a compiler (in any language) will get you this knowledge also. I've never learned C to any depth, although I've written some, and I've written device drivers and other kernel-level stuff (mostly various assemblers, years ago), as well as debugged other people's HLL code by looking at the emitted machine code.
