Going back to bone simple...
Have you tried a Factory Reset?
(I'm assuming your G11 has a Gemini II. Because I am ignorant if this is available with a Gemini I.)
Just thought I would through that in there. (Not that I'm ignorant. That maybe a Factory Reset could help flush any turds out of the controller.)
One other thing I've made a habit of is to use the Quick Start. It gives me a review of my settings, then drops me at a cold start.
But with the assurance my settings are hunky-dory, before I start. ;^)
