No, I had not done that, in fact, I didn't even know I needed those 
modules. I use MODULES_OVERRIDE so I had to add dtrace, cyclic, and 
opensolaris to the list.

In any case ... It's working now! :)

I'm collecting some data for "normal" atm, then I'll try to get it into 
the situation where intr runs away, and I'll do the same thing again.


Thanks Max and Chris,

Doug
