** Description changed: 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. Since nothing was open and I hadn't done anything since the upgrade yet, I looked at top. There it showed systemd-journal and rsyslog using 100% CPU. I looked at /var/log/syslog and there was a flood of messaging continually being appended of the form: ACPI Error: no handler or method for gpe ... disabling event ... The system was still somewhat usable, so I tried checking for updates, but there wasn't anything to update. 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: + USER PID 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-firmware 1.161.1 + 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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1653327 Title: 100% cpu usage with 4.8 kernel after upgrade to 16.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1653327/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
