I have great news! The system is now booting properly! No more 20 minute wait to login! I noticed it with the update to the 4.4.0-42 kernel. So, this issue might have been fixed with either that kernel update or the previous, 4.4.0-38 kernel update.
In any event, this is no longer an issue and this bug report can be closed out. I'll close it, if I can. :) Thanks! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1598935 Title: Ubuntu 16.04 won't properly boot due to radeon module issue To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1598935/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
