I've played with systemtap around 2011/2012, with RHEL 5 and versions of Fedora at the time, and I could easily get it to kernel panic. I went on to their irc channel to report the problems and got some fixes, but in the end it still wasn't stable and I gave up due to lack of time.
I really wanted to get it working. One of my colleagues (who was from Sun) actually left and went to work for Joyent, presumably at least partly because of the frustration with the lack of a dtrace like tool.
