There's no way to bisect this thing - it started happening after 2
hours (first message at 8287.139375 seconds from boot, to be exact).
So far only once, but that's possibly because I've been asleep for the
last eight hours ;)

But yes, it worked before pulling Dave's tree, IOW, I haven't seen
this message on this machine before.

And as mentioned, this is a regular machine, not one of my
preproduction things that tend to have odd silicon or BIOSes.
Bog-standard Core i5 on an Asus P7H57D-V EVO motherboard. The fanciest
part of that machine is the silent case ;)

So I don't _know_ that it was the screen saver that triggered, but I
do know that it started happening while I was out to pick up a kid
from gymnastics. So the screen saver was pretty much the only thing
going on apart from an idle desktop with a few terminals and chrome.

And it's not even a 3D screen saver or anything graphically fancy,
it's just the "show random photos" one (it eventually does blank too,
but I think I've set the blanking interval to an hour or something).
But compiz was on.
