I understand that every user would like every bug they file to be considered "Important".
In this case though we have around 23 people who have confirmed this bug affects them on the three separate bug reports. It causes hanging and forced hard shutdowns at unpredictable times as often as every 15 minutes or so. This means there is a high probability of user data loss and even hardware damage. I respectfully submit that it's reasonable to expect the importance of this to be set to High. -- 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/1813423 Title: Frequent system freezing with i915 error "*ERROR* Atomic update failure on pipe A" Status in linux package in Ubuntu: Confirmed Status in xserver-xorg-video-modesetting package in Ubuntu: New Bug description: My system keeps freezing on a brand new install of Kubuntu 18.10, always with the kern.log error "[drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe A (start=4120234 end=4120235) time 486 us, min 763, max 767, scanline start 760, end 783" I think it's probably a duplicate of these bugs which were closed unresolved: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1660619 (closed as it was on an older version of Ubuntu) https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1671975 (closed because it was a duplicate of the first bug) It happens far more frequently if I have desktop effects turned on, and far less frequently when using a live USB key (at always happens eventually though. Usually once every few hours.) Please advise how I can help triage / test. My system is a new install now, so I'm perfectly willing to modify / reinstall to help testing (I've reinstalled 5 times to test things, but never managed to find a solution) ProblemType: Bug DistroRelease: Ubuntu 18.10 Package: xorg 1:7.7+19ubuntu8 ProcVersionSignature: Ubuntu 4.18.0-13.14-generic 4.18.17 Uname: Linux 4.18.0-13-generic x86_64 ApportVersion: 2.20.10-0ubuntu13.1 Architecture: amd64 BootLog: Error: [Errno 13] Permission denied: '/var/log/boot.log' CompositorRunning: None CurrentDesktop: KDE Date: Sat Jan 26 14:19:52 2019 DistUpgraded: Fresh install DistroCodename: cosmic DistroVariant: ubuntu ExtraDebuggingInterest: No GraphicsCard: Intel Corporation Atom Processor Z36xxx/Z37xxx Series Graphics & Display [8086:0f31] (rev 0e) (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Atom Processor Z36xxx/Z37xxx Series Graphics & Display [103c:227a] InstallationDate: Installed on 2019-01-18 (8 days ago) InstallationMedia: Kubuntu 18.10 "Cosmic Cuttlefish" - Release amd64 (20181017.2) MachineType: Hewlett-Packard HP Pavilion 14 Notebook PC ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.18.0-13-generic root=UUID=2c4bf3d1-1ff2-4345-95c0-c68d0e073df9 ro nogpumanager modprobe.blacklist=nouveau,nvidiafb,nvidia-modeset,nvidia-uvm,nvidia intel_iommu=igfx_off i915.semaphores=1 i915.enable_fbc=0 i915.modeset=1 i915.enable_rc=7 i915.enable_dc=2 i915.enable_ppgtt=3 i915.enable_guc_loading=1 i915.lvds_channel_mode=2 i915.lvds_use_ssc=1 quiet splash vt.handoff=1 SourcePackage: xorg UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 03/18/2015 dmi.bios.vendor: Insyde dmi.bios.version: F.42 dmi.board.asset.tag: Type2 - Board Asset Tag dmi.board.name: 227A dmi.board.vendor: Hewlett-Packard dmi.board.version: 76.35 dmi.chassis.asset.tag: Chassis Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: Hewlett-Packard dmi.chassis.version: Chassis Version dmi.modalias: dmi:bvnInsyde:bvrF.42:bd03/18/2015:svnHewlett-Packard:pnHPPavilion14NotebookPC:pvr096C110800405F10000620180:rvnHewlett-Packard:rn227A:rvr76.35:cvnHewlett-Packard:ct10:cvrChassisVersion: dmi.product.family: 103C_5335KV G=N L=CON B=HP S=PAV X=Null dmi.product.name: HP Pavilion 14 Notebook PC dmi.product.sku: J9L01UA#ABL dmi.product.version: 096C110800405F10000620180 dmi.sys.vendor: Hewlett-Packard version.compiz: compiz N/A version.libdrm2: libdrm2 2.4.95-1 version.libgl1-mesa-dri: libgl1-mesa-dri 18.2.2-0ubuntu1 version.libgl1-mesa-glx: libgl1-mesa-glx 18.2.2-0ubuntu1 version.xserver-xorg-core: xserver-xorg-core 2:1.20.1-3ubuntu2.1 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev N/A version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:18.1.0-1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.917+git20171229-1ubuntu1 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.15-3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1813423/+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
