Did you do a:
kldload dtraceall
on the system? Just dtrace.ko isn't enough to have dtrace work.. What
does dtrace -l say? If you just have dtrace.ko loaded, you'll see
something like:
# dtrace -l
ID PROVIDER MODULE FUNCTION NAME
1 dtrace BEGIN
2 dtrace END
3 dtrace ERROR
if you have dtraceall.ko loaded, you should see many pages of lines..
