Hi again.

I'm not ignoring you.
I've rebuilt the kernel with these patches and
I'm waiting for the messages to show up again.

The only times I've seen them have been after
hibernating and resuming.

I've done several hibernate/restart cycles but
haven't had the messages emitted in the logs yet.

cheers, Joe
