I am sorry to hear you have having some issues with the 4.0.4 BSP. Between the release notes:
http://support.logicpd.co...talid=0&EntryId=2695 and the test notes listed
http://support.logicpd.co...talid=0&EntryId=2696 we try to document any known issues.
Are you using the HDMI to display 1024x768? There is a documented issue with HDMI shown in the release notes (see link above).
If you feel there is something wrong beyond what is listed there, feel free to post again, and I can see that it gets entered into our bug tracking system. If you have an example of how to reproduce your issue, that can help us determine if there is a bug or not.
