@Joseph, both versions can boot up properly. And more, I just found out the latest v4.8.0-34 already can boot up successfully without acpi=off while previous v4.8.0-30 does not.
So looks like that my issue has been fixed in 4.8.0-34. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1635447 Title: Upgraded or Live USB 16.10 hangs at boot up blank purple screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1635447/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
