could that be a driver issue
The last stable release is 2.7.5. Maybe try an upgrade first?

Don't be an asshat. 2.7.5 is the latest release. It is not stable for everyone. Just because it works for you, doesn't mean that everyone else should be using it.
Wow... rough night?
The last stable release in the 2.6 series was 2.6.6. The current last stable release is 2.7.5. Maybe help Kano and Con with debugging info if the versions you are using are stable and the latest ones don't work?
