I have been looking at the patch - and in as much as it has been posted quite a long time ago, I was wondering if it had been "merged" with the present src ? If that is not the case - then I have to admit the following; I have never before 'added a patch'. So I would need to know how I do that (feel very silly and novice like, asking this) ... > You can try a stripped down kernel test, but I doubt it would solve > the problem.

I've tried a similar stripped-down kernel approach and it doesn't seem to make a whole lot of a difference (removed everything which I deemed safe and rebooted + kldloaded various modules):-/ But it would probably be interesting to know if there are any significant differences between 6.0 Release, Stable and Current ?
