Hi Max,
It was some hard time for me, sorry for late response.
I did enabled KDB, DDB and WITNESS on the same sources.
Unfortunately there was just plain hangs once some GRE was trying to
get through (netgraph? PF? routing?)
With these options enabled, hangs are much more often than without them.
Once hung, no way to break into debugger, no panics, numlock not
changing lights on keyboard, mouse not responding, hdd silent, network
not available, nothing.
3 different HW platforms were tried (all of them were UP+i386+32bit).
Highest CPU temperature was 52C. No chance to go with 7.2-PRERELEASE.
Had to downgrade to 7.1-RELEASE.
