You are using very new Alpha Software with a new Linux Kernel.
So you have to be prepared for issues and bugs because it is not what you would call stable software.
Try using a LE 8.2.x version if you do not want to be a Guinea pig and experiment.
I would say the same to anyone using any sort of Alpha software on any hardware platform.
Then you'd attribute my problem soley to the build i am using? or is this a default reaction to any problem you face with this build?
