Hi Bjorn This is v2 of my patch to fix the disable_acs_redir paramater. Per our discussion I've found a much better way which can be applied to the resource_alignment paramater. Thus, I've included a second patch that removes the static buffer used there. I'd appreciate it if the first patch can be applied quickly to fix the bug I caused. The second patch can go in slowly.
