Michael Gratton, thank you for reporting this and helping make Ubuntu better.
Could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel- ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue. If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where X, Y, and Z are numbers corresponding to the kernel version. If the mainline kernel does not fix the issue, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Description changed: On my MacbookPro12,1 with Wily and Linux 4.2, by default the kernel successfully suspends but then immediately resumes again. The problem - seems to be the XHCI controller causing spurious ACPI wakeups. After - disabling it using the following command: - - > # echo XHC1 > /proc/acpi/wakeup - - The kernel remains suspended after entering sleep. (Via - https://wiki.archlinux.org/index.php/MacBook#Suspend_and_Hibernate) + seems to be the XHCI controller causing spurious ACPI wakeups. Also, the Broadcom wifi module seems to have problems with suspend/resume, so I am also unloading the `brcmfmac` module prior to suspend and loading it again after resume. - Bug reported per per request by @penalvch in bug #1487919. + WORKAROUND: Disable XHC1 prior to sleeping: + > # echo XHC1 > /proc/acpi/wakeup ProblemType: Bug DistroRelease: Ubuntu 15.10 Package: linux-image-4.2.0-16-generic 4.2.0-16.19 ProcVersionSignature: Ubuntu 4.2.0-16.19-generic 4.2.3 Uname: Linux 4.2.0-16-generic x86_64 ApportVersion: 2.19.1-0ubuntu2 Architecture: amd64 AudioDevicesInUse: - USER PID ACCESS COMMAND - /dev/snd/controlC1: mjg 1441 F.... pulseaudio - /dev/snd/controlC0: mjg 1441 F.... pulseaudio + USER PID ACCESS COMMAND + /dev/snd/controlC1: mjg 1441 F.... pulseaudio + /dev/snd/controlC0: mjg 1441 F.... pulseaudio CurrentDesktop: GNOME Date: Mon Oct 19 18:13:15 2015 HibernationDevice: RESUME=UUID=bc879a1f-ac27-48ae-82dd-3c81b7307dd0 InstallationDate: Installed on 2015-07-22 (89 days ago) InstallationMedia: Ubuntu-GNOME 15.04 "Vivid Vervet" - Release amd64 (20150422) Lsusb: - Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub - Bus 001 Device 003: ID 05ac:0273 Apple, Inc. - Bus 001 Device 002: ID 05ac:8290 Apple, Inc. - Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub + Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub + Bus 001 Device 003: ID 05ac:0273 Apple, Inc. + Bus 001 Device 002: ID 05ac:8290 Apple, Inc. + Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub MachineType: Apple Inc.
