It might be that the EHCI does not support addressing 16GBytes of RAM, or even 4GB's of RAM. In your case the EHCI will be moving data using bounce buffers in the lower 4GBytes of RAM. Try reducing the amount of RAM to 2GBytes. Are you able to extract a backtrace from the crash. Sounds like a DMA/Busdma problem. --HPS
