Linus makes our life a bit harder.
I missed this one earlier. ATI will need to modify their driver code. The non-GPL portion is trying to access GPL-only kernel code, so that portion needs to move into ATI's shim. Nothing is broken here, this is the expected result occasionally. You implicitly agreed to have to put up with this occasionally when you decided to use fglrx, and also when you decided to use the Linux kernel. See: stable_api_nonsense.txt or you could just use radeon and all these troubles go away. -- Alan McKinnon [email protected]
