Okay. I won't worry about the messages then.
I mentioned the suspend/resume problem only because it
actually worked correctly when using option ForcePCIMode;
I was shocked when it did and was hoping that your fix for
AGP accelerated DRI would pull off the same trick.
I should note here that I didn't see any of the panics other
people did before your last iteration of the fix. I'm guessing
it is because I didn't actually compile the code into my kernel
but instead let it build new modules. Any idea why that would
make the difference?
Sean

Suspend/resume is doesn't work well. You might get lucky with the
-current DRM with XFree86-4-Server-snap.

That printout happens whenever an mpsafe interrupt handler is
installed. It gets installed upon initializing the DRI in the server.
I don't think any drivers do it more often. It may happen frequently if
glxgears is your only app running, in which case you'll get a server
regenerate on exit of glxgears.
