It either used to run init tables and now doesn't, or conversely didn't use to and now does. Would you mind running a "working" kernel with nouveau.debug=debug and see if it ever says "bios: running init tables"? If it does, you can probably make the new kernels work by adding nouveau.config=NvForcePost=1 . If it previously didn't run the tables and now does, there's no config-line way of overriding it.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
