Is there any reasonable tutorial for using kgdb with the bvmdebug kernel option? A couple of folks I know have run into issues trying to debug a FreeBSD stable/9 kernel from their bhyve hosting machine (running stable/10). In particular, the loadable modules that are in use in the stable/9 kernel are being "troublesome" to get to the point where source-level debugging actually works. Even a pointer to a couple of "worked" examples might be useful. I've read this: http://people.freebsd.org/~jhb/papers/bsdcan/2008/article/node4.html but not all the techniques in there appear to work properly. -Kurt
