One more - I remember seeing somewhere an explicit kernel-stack overflow Oops message, but I don't remember exactly under which circomstances, which kernel version, etc. Are kernel-stack overflows ever / always traced explicitely? Thought there should be a kernel-hacking option for that - but no, doesn't seem to be.
