The "pcie_aspm=off" kernel parameter hides a problem. I would really like to fix the underlying problem so the parameter isn't needed.
If anybody sees this problem and is willing to help fix it, please open a bug report at https://bugzilla.kernel.org/, product Drivers/PCI, mention the hardware platform, and attach: - complete dmesg log (I assume this will include some Correctable Errors) - output of "sudo lspci -vv" If booting with the "pcie_aspm=off" kernel parameter makes a difference, please also attach similar dmesg and lspci output for this boot. This seems similar to https://bugzilla.kernel.org/show_bug.cgi?id=215027, which we originally thought was related to Intel VMD and/or the Samsung NVMe device you have, but I now suspect we might have an ASPM configuration problem. ** Bug watch added: Linux Kernel Bug Tracker #215027 https://bugzilla.kernel.org/show_bug.cgi?id=215027 -- 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/2043665 Title: Hundreds of errors per second: kernel: pcieport 0000:00:1c.3: PCIe Bus Error Status in linux package in Ubuntu: Expired Bug description: After a fresh 23.10 install I have noticed that booting up my PC in the morning was taking a long time. Checking journalctl there are hundreds of warnings generated every second, and not only at boot time (see below). Searching for this problem I found a stopgap solution by adding this instruction in GRUB: pcie_aspm=off However, as a plain Ubuntu user I should be having this problem of long boot times and edit GRUB to "fix" it, when the problem captured in the log isn't even fixed, I just avoided it with instruction. This is why I'm reporting it in case it helps find the original cause. Previously I was running 23.04 on the same PC and booting times were short, just normal. I believe this is a new problem even when the hardware is the same and I haven't done any changes apart from upgrading. The errors are all the same: Nov 16 09:26:37 quiet kernel: pcieport 0000:00:1c.3: AER: Corrected error received: 0000:00:1c.3 Nov 16 09:26:37 quiet kernel: pcieport 0000:00:1c.3: PCIe Bus Error: severity=Corrected, type=Physical Layer, (Receiv> Nov 16 09:26:37 quiet kernel: pcieport 0000:00:1c.3: device [8086:7abb] error status/mask=00000001/00002000 Nov 16 09:26:37 quiet kernel: pcieport 0000:00:1c.3: [ 0] RxErr (First) Nov 16 09:26:37 quiet kernel: pcieport 0000:00:1c.3: AER: Corrected error received: 0000:00:1c.3 Nov 16 09:26:37 quiet kernel: pcieport 0000:00:1c.3: PCIe Bus Error: severity=Corrected, type=Physical Layer, (Receiv> Nov 16 09:26:37 quiet kernel: pcieport 0000:00:1c.3: device [8086:7abb] error status/mask=00000001/00002000 Nov 16 09:26:37 quiet kernel: pcieport 0000:00:1c.3: [ 0] RxErr (First) ProblemType: Bug DistroRelease: Ubuntu 23.10 Package: linux-image-6.5.0-10-generic 6.5.0-10.10 ProcVersionSignature: Ubuntu 6.5.0-10.10-generic 6.5.3 Uname: Linux 6.5.0-10-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.27.0-0ubuntu5 Architecture: amd64 CRDA: N/A CasperMD5CheckResult: unknown CurrentDesktop: ubuntu:GNOME Date: Thu Nov 16 09:38:28 2023 InstallationDate: Installed on 2023-11-13 (2 days ago) InstallationMedia: Ubuntu 23.10.1 "Mantic Minotaur" - Release amd64 (20231016.1) MachineType: {report['dmi.sys.vendor']} {report['dmi.product.name']} ProcEnviron: LANG=en_US.UTF-8 PATH=(custom, no user) SHELL=/bin/bash TERM=xterm-256color XDG_RUNTIME_DIR=<set> ProcFB: 0 EFI VGA ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-6.5.0-10-generic root=UUID=fa113624-262e-4625-ba8b-eabf66ab696c ro pcie_aspm=off RelatedPackageVersions: linux-restricted-modules-6.5.0-10-generic N/A linux-backports-modules-6.5.0-10-generic N/A linux-firmware 20230919.git3672ccab-0ubuntu2.2 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 12/03/2021 dmi.bios.release: 5.24 dmi.bios.vendor: American Megatrends International, LLC. dmi.bios.version: A.10 dmi.board.asset.tag: Default string dmi.board.name: MPG Z690 FORCE WIFI (MS-7D30) dmi.board.vendor: Micro-Star International Co., Ltd. dmi.board.version: 2.0 dmi.chassis.asset.tag: Default string dmi.chassis.type: 3 dmi.chassis.vendor: Micro-Star International Co., Ltd. dmi.chassis.version: 2.0 dmi.modalias: dmi:bvnAmericanMegatrendsInternational,LLC.:bvrA.10:bd12/03/2021:br5.24:svnMicro-StarInternationalCo.,Ltd.:pnMS-7D30:pvr2.0:rvnMicro-StarInternationalCo.,Ltd.:rnMPGZ690FORCEWIFI(MS-7D30):rvr2.0:cvnMicro-StarInternationalCo.,Ltd.:ct3:cvr2.0:skuDefaultstring: dmi.product.family: Default string dmi.product.name: MS-7D30 dmi.product.sku: Default string dmi.product.version: 2.0 dmi.sys.vendor: Micro-Star International Co., Ltd.
