That's OK, I mean I knew that before :-))

But I seem to remember reading something about that the interrupt driven 
PTec drivers shouldn't stop the system while accessing the disc anymore
(unlike the even earlier polling ones).

That is, my system goes totally unusuable whenever I start a command that 
accesses the disc.
So do all currently made kernels use the interrupt powertec driver ?

Or are these hiccups caused by something else ???

Kind regards,
