mscdex, the next step is to fully reverse commit bisect from kernel 4.8 to 4.9 in order to identify the last bad commit, followed immediately by the first good one. Once this good commit has been identified, it may be reviewed for backporting. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ? Please note, finding adjacent kernel versions, or providing a commit from a kernel version bisect is not fully commit bisecting. Also, the kernel release names are irrelevant for the purposes of bisecting. It is most helpful that after the fix commit (not kernel version) has been identified, you then mark this report Status Confirmed.

[Kernel-packages] [Bug 1653327] Re: 100% cpu usage with 4.8 kernel after upgrade to 16.10
mscdex, thank you for reporting this and helping make Ubuntu better. In order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following: 1) The one to test is at the very top line at the top of the page (not the daily folder). 2) The release names are irrelevant. 3) The folder time stamps aren't indicative of when the kernel actually was released upstream. 4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . If testing on your main install would be inconvenient, one may: 1) Install Ubuntu to a different partition and then test this there. 2) Backup, or clone the primary install. 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, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists. 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. Also, you don't need to apport-collect further unless specifically requested to do so. It is most helpful that after testing of the latest upstream kernel is complete, you mark this report Status Confirmed. Lastly, to keep this issue relevant to upstream, please continue to test the latest mainline kernel as it becomes available.

Since I never encountered this error before, I tried installing a mainline kernel (4.9) from the Ubuntu mainline kernel PPA. I booted into the new, mainline kernel and no more 100% CPU usage. The only problem with using this kernel is that I can't use VirtualBox anymore because dkms has a compilation issue when building against the 4.9 kernel. Before upgrading to 16.10, I was using Lubuntu 16.04 with whatever the latest 4.4 kernel was at the time that 16.10 was released, which also worked just fine. - The current (as of this writing) 4.8 kernel that is still causing - problems is 4.8.0-32. + The current (as of this writing) 4.8 kernel that is still causing problems is 4.8.0-32. + --- + ApportVersion: 2.20.3-0ubuntu8.2 + Architecture: amd64 + AudioDevicesInUse: + USERPID ACCESS COMMAND + /dev/snd/controlC0: mscdex 1812 F pulseaudio + /dev/snd/controlC1: mscdex 1812 F pulseaudio + CurrentDesktop: LXDE + DistroRelease: Ubuntu 16.10 + InstallationDate: Installed on 2013-12-07 (1119 days ago) + InstallationMedia: Lubuntu 13.10 "Saucy Salamander" - Release amd64 (20131016) + MachineType: Sony Corporation SVP13213CXB + Package: linux (not installed) + ProcFB: 0 inteldrmfb + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.8.0-32-generic root=UUID=97c33b42-d845-488d-9a1f-d62e03702b16 ro quiet splash libata.force=noncq acpi_backlight=vendor vt.handoff=7 + ProcVersionSignature: Ubuntu 4.8.0-32.34-generic 4.8.11 + RelatedPackageVersions: + linux-restricted-modules-4.8.0-32-generic N/A + linux-backports-modules-4.8.0-32-generic N/A + linux-firmware1.161.1 + Tags: yakkety + Uname: Linux 4.8.0-32-generic x86_64 + UpgradeStatus: Upgraded to yakkety on 2016-12-17 (14 days ago) + UserGroups: adm audio cdrom dip lpadmin netdev plugdev sambashare sudo vboxusers wireshark + _MarkForUpload: True + dmi.bios.date: 11/05/2013 + dmi.bios.vendor: American Megatrends Inc. + dmi.bios.version: R1041V7 + dmi.board.asset.tag: N/A + dmi.board.name: VAIO + dmi.board.vendor: Sony Corporation + dmi.board.version: N/A + dmi.chassis.asset.tag: N/A + dmi.chassis.type: 10 + dmi.chassis.vendor: Sony Corporation + dmi.chassis.version: N/A + dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvrR1041V7:bd11/05/2013:svnSonyCorporation:pnSVP13213CXB:pvrC60C2CVE:rvnSonyCorporation:rnVAIO:rvrN/A:cvnSonyCorporation:ct10:cvrN/A: + dmi.product.name: SVP13213CXB + dmi.product.version: C60C2CVE + dmi.sys.vendor: Sony Corporation ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/1653327/+attachment/4798505/+files/AlsaInfo.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1653327 Title: 100% cpu usage with 4.8 kernel after upgrade to 16.10 Status in linux package in Ubuntu: Confirmed Bug description: After upgrading my Sony Vaio Pro 13 to Lubuntu 16.10 and logging in for the first time, I noticed the fans were spinning crazy fast.
