Hey Darran; first million thanks for your work on porting DTrace :)
Second, I can update the wiki page, don't waste time on such mundane tasks.
Third, I get a 100% reproducible kernel panic, every time I use an fbt
It doesn't matter which function I hook into, the system will crash
Unfortunately, I don't have a swap partition (epic fail), so I can't
set up a dump device and provide you a core.
Mind that netbsd is running as virtualbox guest in an opensolaris host.
Again, thanks for your work.
