I had the same issue (12.04 with kernel 3.5 and the new dkms module). See here: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/923809/comments/22
Applying the user-ioctl.patch patch found here: https://aur.archlinux.org/packages.php?ID=19514 removed those two error/warning messages. Everything else continued to work OK.
