There are a number of good sounding suggestions in there.
DTrace is pure magic. It would be well worth your time to install
Solaris 10 just to try out DTrace for a day. Keep in mind,
however, that it took them several man-years to develop just for
sparc64 and x86, so we're not talking about a port of it any time
soon...

I haven't seen above well yet. But A article says that DTrace sounds like 30,000 lines of debug print. I have written about 50 lines of debug print in my 4.10-R kernel to chase my umass issue. If the output of it exists on a trace log file, It may be one of DTrace feature. I saw the some sort of debug print lines in the kernel source of 4.10-R. If you enable them and gather the information to a file, it may be nearly equal DTrace. But I can't warrant or guarantee you the performance. DTrace may be a kinda elegant debug mode kernel, I guess.
