En-Wei Wu, After a lot of trial and error, I was able to build linux-next and disable secure boot so I could run the kernel.
I confirmed my copy of linux-next already included the referenced patch. I am able to now report that it appears to solve the high CPU complaint. While there still are interrupts as Greg is reporting, I am so happy to see the CPU is idle. My solution until today has been to rmmod after boot with a root's crontab: --- $ sudo crontab -l #Ansible: kernel bug @reboot sleep 10 && rmmod ucsi_acpi --- $ grep . -r /sys/firmware/acpi/interrupts/ | awk '$2 > 0' /sys/firmware/acpi/interrupts/sci: 1247 /sys/firmware/acpi/interrupts/gpe_all: 1247 /sys/firmware/acpi/interrupts/gpe17: 1247 EN enabled unmasked $ lsmod|egrep ucsi typec_ucsi 61440 0 typec 114688 1 typec_ucsi $ sudo modprobe -a /lib/modules/6.12.0-rc5-next-20241030-custom/kernel/drivers/usb/typec/ucsi/ucsi_acpi.ko $ lsmod|egrep ucsi ucsi_acpi 12288 0 typec_ucsi 61440 1 ucsi_acpi typec 114688 1 typec_ucsi $ grep . -r /sys/firmware/acpi/interrupts/ | awk '$2 > 0' /sys/firmware/acpi/interrupts/sci: 1319 /sys/firmware/acpi/interrupts/gpe_all: 1319 /sys/firmware/acpi/interrupts/gpe17: 1319 EN enabled unmasked $ uptime 10:01:36 up 8 min, 2 users, load average: 0.08, 0.09, 0.07 $ uname -a Linux victus 6.12.0-rc5-next-20241030-custom #4 SMP PREEMPT_DYNAMIC Fri Nov 1 08:33:33 EDT 2024 x86_64 x86_64 x86_64 GNU/Linux Thank you for your continued efforts, and Greg Kroah-Hartman <gre...@linuxfoundation.org> for the commit. -- 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/2073538 Title: kacpi_notify high cpu on interrupt gpe17 Status in linux package in Ubuntu: Incomplete Bug description: Picked up a HP laptop during July sales, and found the CPU soars to 80+ with kacpi_notify hitting GPE17. I would like some help finding the cause. Google searches were vague about masking the interrupt which did NOT help. If we can find what is calling the interrupts maybe we can better document a solution. top - 20:00:05 up 10 min, 1 user, load average: 86.24, 76.27, 42.44 Tasks: 453 total, 2 running, 451 sleeping, 0 stopped, 0 zombie %Cpu(s): 0.1 us, 8.5 sy, 0.0 ni, 91.4 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st MiB Mem : 62040.5 total, 51595.7 free, 3166.0 used, 8146.3 buff/cache MiB Swap: 0.0 total, 0.0 free, 0.0 used. 58874.4 avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 127 root 20 0 0 0 0 D 1.3 0.0 0:03.71 [kworker/11:1+kacpi_notify] 280 root 20 0 0 0 0 D 1.3 0.0 0:06.63 [kworker/5:5+kacpi_notify] 314 root 20 0 0 0 0 D 1.3 0.0 0:06.68 [kworker/5:12+kacpi_notify] ubuntu@ubuntu:~$ grep . -r /sys/firmware/acpi/interrupts/ | awk '$2 > 0' /sys/firmware/acpi/interrupts/sci: 1907 /sys/firmware/acpi/interrupts/gpe_all: 1907 /sys/firmware/acpi/interrupts/gpe17: 1907 EN enabled unmasked ProblemType: Bug DistroRelease: Ubuntu 24.04 Package: linux-image-6.8.0-31-generic 6.8.0-31.31 ProcVersionSignature: Ubuntu 6.8.0-31.31-generic 6.8.1 Uname: Linux 6.8.0-31-generic x86_64 NonfreeKernelModules: zfs ApportVersion: 2.28.1-0ubuntu2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/seq: ubuntu 2813 F.... pipewire /dev/snd/controlC1: ubuntu 2815 F.... wireplumber /dev/snd/controlC0: ubuntu 2815 F.... wireplumber /dev/snd/controlC2: ubuntu 2815 F.... wireplumber CRDA: N/A CasperMD5CheckResult: unknown CasperVersion: 1.498 CloudArchitecture: x86_64 CloudID: nocloud CloudName: unknown CloudPlatform: nocloud CloudSubPlatform: seed-dir (/var/lib/cloud/seed/nocloud) CurrentDesktop: ubuntu:GNOME Date: Thu Jul 18 19:52:46 2024 LiveMediaBuild: Ubuntu 24.04 LTS "Noble Numbat" - Release amd64 (20240424) MachineType: HP Victus by HP Gaming Laptop 15-fb2xxx ProcEnviron: LANG=C.UTF-8 PATH=(custom, no user) SHELL=/bin/bash TERM=xterm-256color XDG_RUNTIME_DIR=<set> ProcFB: 0 amdgpudrmfb ProcKernelCmdLine: BOOT_IMAGE=/casper/vmlinuz --- quiet splash RelatedPackageVersions: linux-restricted-modules-6.8.0-31-generic N/A linux-backports-modules-6.8.0-31-generic N/A linux-firmware 20240318.git3b128b60-0ubuntu2 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 05/20/2024 dmi.bios.release: 15.3 dmi.bios.vendor: AMI dmi.bios.version: F.03 dmi.board.asset.tag: Base Board Asset Tag dmi.board.name: 8C2F dmi.board.vendor: HP dmi.board.version: 04.14 dmi.chassis.type: 10 dmi.chassis.vendor: HP dmi.chassis.version: Chassis Version dmi.ec.firmware.release: 4.14 dmi.modalias: dmi:bvnAMI:bvrF.03:bd05/20/2024:br15.3:efr4.14:svnHP:pnVictusbyHPGamingLaptop15-fb2xxx:pvr:rvnHP:rn8C2F:rvr04.14:cvnHP:ct10:cvrChassisVersion:skuA14MNUA#ABA: dmi.product.family: 103C_5335M7 HP Victus dmi.product.name: Victus by HP Gaming Laptop 15-fb2xxx dmi.product.sku: A14MNUA#ABA dmi.sys.vendor: HP To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2073538/+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
