Well, than make different point. Stuff did not change for 3 years in a
row, and still does not need special handling of a specific subsystem
in the driver core.

Sure, and it still does.

Yes, new stuff exposes old bugs, that's normal business. But there is
zero reason not to fix the problem then, but to introduce plain wrong
hacks in the wrong place.

Btw, I hope you guys stop the personal affronts in your mails, and
start focusing on a proper solution for the problem. I'll stop
responding if this will not go back to a discussion about technical
details.

Thanks,
Kay
