Why are you bouncing ? | | qlogicisp. Because the driver is crap? ;-) The question is, does that make your testing better or worse in terms of checking the new code? Clearly you have done a good job of checking the "disk can't keep up" case, is there a need to test further with a much higher transaction rate? I would assume that if there were lock issues they would have shown up, which is probably all that's needed. -- bill davidsen CTO, TMR Associates, Inc Doing interesting things with little computers since 1979.
