I have all sorts of ugly problems with the clcs on a *non* MP kernel,
on my IBM T20 laptop. Often the driver spews uncontrollably during
autoconfig, preventing the system from booting, and I have occasional
problems with noise being introduced into sound play which booting
under windows and rebooting with NetBSD fixes. All of these point to
failures to initialize the chip properly at various points.
