Yes I can see those kernel errors causing delays in your logs. They seem to be referring to the motherboard:
00:1c.5 PCI bridge [0604]: Intel Corporation Sunrise Point-LP PCI Express Root Port #6 [8086:9d15] (rev f1) (prog-if 00 [Normal decode]) That's probably either a hardware fault or a kernel bug. If it is a hardware fault then it might be limited to just your wifi card or something removable like that... ** Summary changed: - booting issue + "PCIe Bus Error: severity=Corrected, type=Physical Layer, (Receiver ID)" causing boot delays ** Package changed: xorg (Ubuntu) => linux (Ubuntu) -- 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/1849540 Title: "PCIe Bus Error: severity=Corrected, type=Physical Layer, (Receiver ID)" causing boot delays Status in linux package in Ubuntu: Confirmed Bug description: ubuntu shows pci bus error severity=corrected when shutting down takes time for login page to pop up ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: xorg 1:7.7+19ubuntu7.1 ProcVersionSignature: Ubuntu 5.0.0-31.33~18.04.1-generic 5.0.21 Uname: Linux 5.0.0-31-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.7 Architecture: amd64 BootLog: Error: [Errno 13] Permission denied: '/var/log/boot.log' CompositorRunning: None CurrentDesktop: ubuntu:GNOME Date: Wed Oct 23 13:32:16 2019 DistUpgraded: Fresh install DistroCodename: bionic DistroVariant: ubuntu GraphicsCard: Intel Corporation Device [8086:5921] (rev 06) (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc.
