But I can't understand why this patch introduced such a bug. In the changelog of the revert patch you wrote that you forgot how pointers work (:-D), but I think I forgot either (if ever known :P). Do you have any idea of what happened? This topic could give us all deeper understanding of kernel memory management. Thank you in advance, fabio
