After installing Jaunty, I had the same problem as described there : https://bugs.launchpad.net/ubuntu/+source/linux/+bug/71004 (a white screen after shutdown which start to darken in some area...)
I removed the 'splash' option in menu.lst but kept the 'quiet' option. Instead of a white screen, I got the problem described in this bug by pierreblueher and WiFi Ed. After removing the 'quiet' option, the bug reappeared only in some rare occasion. When the computer shutdown succesfully, I can read in the console : "iwl3945: Error : Response NULL in 'REPLY_ADD_STA'". I have Ubuntu Jaunty with kernel 2.6.28-13 install on a Dell Inspiron 1520. As you can see in the error message, I have an intel 3945 wireless card. I hope that can help you solving this bug. -- failed to stop md devices on jaunty restart or shutdown https://bugs.launchpad.net/bugs/350207 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
