I submitted a bug on this issue, it looks like you can reference other bugs when you submit one, so everyone having this issue could possibly link mine and submit their own hardware config. It sounds like it's widespread though, so I'm not sure if that would help or hinder. I'd hate to bury the

I was just looking to see if it is a known problem before I submit it as a bug. What would be the best category to submit the bug under? I am not sure if it is driver/kernel issue. I would be more than glad to help. One of the machines is a test environment and I can run any dumps/debug versions
