** Description changed: 1) Ubuntu Release No LSB modules are available. Description: Ubuntu 24.04.2 LTS Release: 24.04 2) Package version 6.8.0-54.56 3) What you expected to happen I expected the system to be able to boot with ACPI. 4) What happened instead The booting process got stuck halfway through (about when the console adjusts it's resolution) if the kernel wasn't given the "acpi=off" parameter. However, with this parameter, SMP doesn't work and my CPU is reduced to a single core from 16 with HT. I followed this guide for troubleshooting: https://wiki.ubuntu.com/DebuggingACPI The system refused to boot even with "acpi=ht". + --- + ProblemType: Bug + AlsaVersion: Advanced Linux Sound Architecture Driver Version k6.8.0-54-generic. + AplayDevices: Error: [Errno 2] No such file or directory: 'aplay' + ApportVersion: 2.28.1-0ubuntu3.3 + Architecture: amd64 + ArecordDevices: Error: [Errno 2] No such file or directory: 'arecord' + AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/timer', '/dev/snd/seq', '/dev/snd/pcmC0D3p', '/dev/snd/pcmC0D7p', '/dev/snd/hwC0D0', '/dev/snd/controlC0', '/dev/snd/by-path', '/dev/snd/pcmC1D0p', '/dev/snd/pcmC1D0c', '/dev/snd/pcmC1D1p', '/dev/snd/pcmC1D2c', '/dev/snd/hwC1D0', '/dev/snd/controlC1'] failed with exit code 1: + CRDA: N/A + Card0.Amixer.info: Error: [Errno 2] No such file or directory: 'amixer' + Card0.Amixer.values: Error: [Errno 2] No such file or directory: 'amixer' + Card1.Amixer.info: Error: [Errno 2] No such file or directory: 'amixer' + Card1.Amixer.values: Error: [Errno 2] No such file or directory: 'amixer' + CasperMD5CheckResult: pass + DistroRelease: Ubuntu 24.04 + InstallationDate: Installed on 2025-02-27 (5 days ago) + InstallationMedia: Ubuntu-Server 24.04.1 LTS "Noble Numbat" - Release amd64 (20240827) + IwConfig: Error: [Errno 2] No such file or directory: 'iwconfig' + MachineType: ASUS System Product Name + Package: linux (not installed) + ProcFB: 0 simpledrmdrmfb + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-6.8.0-54-generic root=UUID=9259c67a-bfe3-40d8-ba70-ac06402f21b2 ro acpi=off + ProcVersionSignature: Ubuntu 6.8.0-54.56-generic 6.8.12 + RelatedPackageVersions: + linux-restricted-modules-6.8.0-54-generic N/A + linux-backports-modules-6.8.0-54-generic N/A + linux-firmware 20240318.git3b128b60-0ubuntu2.9 + RfKill: Error: [Errno 2] No such file or directory: 'rfkill' + Tags: noble + Uname: Linux 6.8.0-54-generic x86_64 + UnreportableReason: This report is about a package that is not installed. + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: N/A + _MarkForUpload: False + acpidump: + + dmi.bios.date: 09/29/2024 + dmi.bios.release: 5.17 + dmi.bios.vendor: American Megatrends Inc. + dmi.bios.version: 3611 + dmi.board.asset.tag: Default string + dmi.board.name: PRIME B550-PLUS + dmi.board.vendor: ASUSTeK COMPUTER INC. + dmi.board.version: Rev X.0x + dmi.chassis.asset.tag: Default string + dmi.chassis.type: 3 + dmi.chassis.vendor: Default string + dmi.chassis.version: Default string + dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr3611:bd09/29/2024:br5.17:svnASUS:pnSystemProductName:pvrSystemVersion:rvnASUSTeKCOMPUTERINC.:rnPRIMEB550-PLUS:rvrRevX.0x:cvnDefaultstring:ct3:cvrDefaultstring:skuSKU: + dmi.product.family: To be filled by O.E.M. + dmi.product.name: System Product Name + dmi.product.sku: SKU + dmi.product.version: System Version + dmi.sys.vendor: ASUS ** Attachment added: "AlsaDevices.txt" https://bugs.launchpad.net/bugs/2100778/+attachment/5862239/+files/AlsaDevices.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2100778 Title: Asus Prime B550 plus requires acpi=off which turns off SMP To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2100778/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
