i'm interested in paring down the possible kernel debugging techniques to the 2 (or 3) most valuable ones, and trying to avoid unnecessary duplication. this is for a tutorial i'm planning on giving in the near future. at the high end, i'm going to cover "systemtap". but below that, what do people consider the most useful tools? (and i'd like to restrict it to tools that don't require extra H/W or a second host, just to keep things simple.) gdb? kdb? kgdb? others? i'm open to recommendations. thanks. rday -- Kernelnewbies: Help each other learn about the Linux kernel.
