Andreas: The problem is in the kernel, you need to patch that one. Also, if you don't have the exact same machine there's a good chance that you have a different bug (but similar symptoms). Please open a new bug report in that case, we can easily close duplicates once we have enough evidence, but untangling different bugs mixed into one report is far more messy.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
