AceLan Kao, First, I downloaded the image and modules:
$ wget https://kernel.ubuntu.com/mainline/v6.11-rc1/amd64/linux-image-unsigned-6.11.0-061100rc1-generic_6.11.0-061100rc1.202407281809_amd64.deb $ wget https://kernel.ubuntu.com/mainline/v6.11-rc1/amd64/linux-modules-6.11.0-061100rc1-generic_6.11.0-061100rc1.202407281809_amd64.deb Then I installed them: $ sudo dpkg -i ./linux-image- unsigned-6.11.0-061100rc1-generic_6.11.0-061100rc1.202407281809_amd64.deb ./linux- modules-6.11.0-061100rc1-generic_6.11.0-061100rc1.202407281809_amd64.deb Then, a reboot: $ sudo reboot Because the image is unsigned, I had to disable secure-boot, finally getting the laptop booted off of the latest kernel: $ uname -a Linux victus 6.11.0-061100rc1-generic #202407281809 SMP PREEMPT_DYNAMIC Sun Jul 28 22:21:22 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux still, no improvement: $ sudo su - # echo 'file ucsi.c +p' > /proc/dynamic_debug/control # cat /proc/dynamic_debug/control|egrep ucsi drivers/usb/typec/ucsi/ucsi.c:1335 [typec_ucsi]ucsi_connector_change =p "Early connector change event\n" drivers/usb/typec/ucsi/ucsi.c:1996 [typec_ucsi]ucsi_register =p "Registered UCSI interface with version %x.%x.%x" # modprobe ucsi_acpi # dmesg|egrep ucsi [ 144.829593] ucsi_acpi USBC000:00: Registered UCSI interface with version 1.0.0 [ 149.857192] ucsi_acpi USBC000:00: failed to reset PPM!

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
