[...Mark's comments re: clcs lossage...]

-> I have all sorts of ugly problems with the clcs on a *non* MP kernel,

-> 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.

I had this problem `disappear' for a long enough time that I thought it
was gone, only to reppear recently.  I've had the autoconf-time lossage
as you report, as well as lossage related to suspend/recover which end
up with similar symptoms (constant spewage from the driver, seemigly at
a fast enough clip or from a bad enough place (interrupt handler?) that
the machine locks hard).  The machine has also locked up while running
X recently (after being idle for a while, so maybe it was trying to do
a suspend), which I'm also tempted to blame on the clcs.

<AOL> My problems were also on the T20. </AOL>
