Hello Christoph, Great news! All your patches work! I tested all your patches (including the patch '0004-alloc-free.patch' today) and the PASEMI onboard ethernet works and the P5020 board boots without any problems. Thank you for your work! I have a few days off. That means, I will work less and only for the A-EON first level Linux support. I can test again on Thursday next week. Have a nice weekend! Cheers, Christian
