I also see these messages on my Dell 410 Workstation at work and a Dual
PIII Box I use at home to do builds with...they just seem to 'come and go'
with no particular pattern to them...I have just been ignoring them for the
most part...they don't really seem to cause any problems..

This occurs both with and without the gettimeofday Giant-removal patch, so
I am fairly sure it has nothing to do with any of my current work. This is

I don't understand how this code is supposed to handle overflows.
You seem only to be checking to see if the master timecounter has
changed to a different type.

However, I think to be complete we need to make it even less elegant.
The TC module is only flip-flopping between two time counters, which
means that it can flip-flop twice and the test will not work. We need
a generation

Matt,
Easy now, there is more depth to it than that... I have promised myself
to get the timecounter paper written and I'll probably present it at
BSDcon-euro-2002 in Amsterdam if they want to listen to me.
For now, lets concentrate on the PIIX hardware because that's where
the problem seems
If this patch cures the PIIX problem, something I'm not at all convinced
about, it should go in, if not only the comment should go in.
I would like to see the PIIX problem caught on camera, personally.
We're aware of one errata for it already, and we work around it. If

Holy shit. We are
