Loading initial ramdisk ... - A screen with kernel messages, ending in: APCI: EC: interrupt blocked I've encountered the bug in a number of kernels, including: - 4.13.0-32 - 4.13.0-36 - 4.13.0-37 - 4.15.0-24 - 4.15.0-34 - 4.15.0-36 - 4.15.0-38 - 4.15.0-42 - 4.20.0-rc7 I was able to work around the issue by adding noapic to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default grub, e.g.: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noapic" I'm not entirely sure of the consequences of this workaround, but one thing I've noticed is significantly reduced battery life. This bug seems very similar to what's described here for the Thinkpad E485/E585: https://evilazrael.de/node/401 I'll attach screenshots of various times I've encountered this bug over the last year. $ lsb_release -rd Description: Ubuntu 18.04.1 LTS Release: 18.04 $ apt-cache policy linux-image-4.15.0-42-generic linux-image-4.15.0-42-generic: Installed: 4.15.0-42.45 Candidate: 4.15.0-42.45 Version table: *** 4.15.0-42.45 500 500 http://us.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages 500 http://security.ubuntu.com/ubuntu bionic-security/main amd64 Packages 100 /var/lib/dpkg/status ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: linux-image-4.15.0-42-generic 4.15.0-42.45 ProcVersionSignature: Ubuntu 4.15.0-42.45-generic 4.15.18 Uname: Linux 4.15.0-42-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: bryan 2349 F.... pulseaudio CurrentDesktop: XFCE Date: Thu Dec 13 15:31:15 2018 HibernationDevice: RESUME=UUID=4afa8032-cfe5-45f4-a626-738ab33904ac InstallationDate: Installed on 2014-05-08 (1680 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) MachineType: LENOVO 3351CTO ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.15.0-42-generic root=UUID=cffbc87d-956b-4986-94df-b3b64ae5237f ro quiet splash noapic vt.handoff=1 RelatedPackageVersions: linux-restricted-modules-4.15.0-42-generic N/A linux-backports-modules-4.15.0-42-generic N/A linux-firmware 1.173.2 SourcePackage: linux UpgradeStatus: Upgraded to bionic on 2018-07-12 (154 days ago) dmi.bios.date: 06/01/2018 dmi.bios.vendor: LENOVO dmi.bios.version: H6ETA0WW (2.18 ) dmi.board.asset.tag: Not Available dmi.board.name: 3351CTO dmi.board.vendor: LENOVO dmi.board.version: Win8 STD DPK TPG dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvrH6ETA0WW(2.18):bd06/01/2018:svnLENOVO:pn3351CTO:pvrThinkPadT430u:rvnLENOVO:rn3351CTO:rvrWin8STDDPKTPG:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.family: ThinkPad T430u dmi.product.name: 3351CTO dmi.product.version: ThinkPad T430u dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1808418/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
