I suspect port-i386 is a better place for this, but...

I continue to have some minor problems with the clcs driver on my IBM
Thinkpad T-20 -- occasionally, if there are lots of short
open/write/close cycles on the device (typical of things like the
chimes put out by a couple of programs like gaim) the audio gets
totally nuked -- starts sounding, for a random period of time, like
you're listening to a scratchy 78 record. It will stay like that
across reboots (!) unless I boot windows in between.1 Also, when
booting, every once in a while the device starts spewing errors and
nukes autoconfig, forcing a power cycle.

However, both of these are sufficiently minor that I haven't actually
spent time looking for the problem myself, and I don't know of others
who've looked either. My hypothesis is that the device is not being
fully initialized by the NetBSD code (or re-initialized when the
device is reset/first opened/etc.)
