i'm currently digging around in the kernel for a better understanding of interrupts and i'm always on the lookout for high-quality online tutorials i can simply swipe for training courses. any recommendations on really good online coverage of interrupts you know of? even the in-kernel documentation under Doc.../DocBook needs a bit of updating for which i'm going to submit some patches. rday -- ======================================================================== Robert P.
