Albert, as per https://support.apple.com/en-us/HT201518 an update to your computer's buggy, insecure, and outdated BIOS is available (MBP111.0138.B16). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. Also, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-b16 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1578621 Title: Ubuntu 16.04 with kernel 4.4.0-21 freezes at the password prompt upon boot unless acpi=off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1578621/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Joseph, Would appreciate if you could point me to debugging instructions for ACPI. None of the cargo-cult-style parameters I passed to the 4.4* or 4.6* kernels works, other than acpi=off, which is not ideal to say the least. The 4.4.0-21 kernel worked in this macbook pro prior to blessing the partition. One wonders why it can't recognize the keyboard and touchpad anymore, and what is the right way to debug the issue. Thanks very much in advance.

For the record, if GRUB is setup to boot in text mode (so that the graphical desktop does not come up), the keyboard is not working either: the system books all the way to a tty prompt, then, despite the cursor blinking the whole time (never stops blinking, like it does after a few seconds for the graphical password prompt), one cannot type in the username. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1578621 Title: Ubuntu 16.04 with kernel 4.4.0-21 freezes at the password prompt upon boot unless acpi=off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1578621/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.6 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
