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,
