AceLan Kao, In summary, I did not see any improvement, but perhaps some of the extended debugging is helpful. I did the following steps over the course of my work day, so I might have missed a step, but here is the order of what I did:
I added the ubuntu kernel repo: $ sudo add-apt-repository ppa:canonical-kernel-team/ppa I added deb-src: $ sudo sed -i 's/^Types:.*$/& deb-src/' /etc/apt/sources.list.d/canonical-kernel-team-ubuntu-ppa-noble.sources $ sudo apt update I then downloaded the kernel source: $ sudo apt install build-essential $ sudo apt source linux-image-unsigned-$(uname -r) I extracted the source and patched it. $ gunzip linux_6.8.0-43.43.diff.gz $ tar -zxvf linux_6.8.0.orig.tar.gz $ cd ~/linux-6.8 $ patch -p1 < ~/linux_6.8.0-43.43.diff I applied your 2 patch files: $ git apply ~/0001-usb-typec-ucsi_acpi-Add-LG-Gram-quirk.patch $ git apply ~/0002-usb-typec-ucsi_acpi-Add-Victus-by-HP-Gaming-Laptop-1.patch I also hand edited ucsi.c and ucsi_acpi.c, adding in the printk statements from the kernel.org bug 217076: https://bugzilla.kernel.org/attachment.cgi?id=306314&action=diff#a/drivers/usb/typec/ucsi/ucsi_acpi.c_sec1 Finally, I ran make: $ make -C /lib/modules/`uname -r`/build M=$PWD/drivers/usb/typec/ucsi/ next I ran the following series of commands to remove the running kernel modules and insert the new debug ones. $ logger -t DEBUG "rmmod ucsi_acpi.ko"; sudo rmmod ucsi_acpi $ logger -t DEBUG "rmmod typec_ucsi"; sudo rmmod typec_ucsi $ logger -t DEBUG "insmod drivers/usb/typec/ucsi/typec_ucsi.ko"; sudo insmod drivers/usb/typec/ucsi/typec_ucsi.ko $ logger -t DEBUG "echo 'file ucsi.c +p' > /proc/dynamic_debug/control"; sudo sh -c 'echo "file ucsi.c +p" > /proc/dynamic_debug/control' $ logger -t DEBUG "insmod drivers/usb/typec/ucsi/ucsi_acpi.ko"; sudo insmod drivers/usb/typec/ucsi/ucsi_acpi.ko I then plugged in a usb-c plantronics headset, hoping to trigger anything usb-c The CPU is still through the roof! I then removed the kernel modules $ logger -t DEBUG "rmmod ucsi_acpi.ko"; sudo rmmod ucsi_acpi $ logger -t DEBUG "rmmod typec_ucsi"; sudo rmmod typec_ucsi Following this update I will attach a syslog which shows this event. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2073538 Title: kacpi_notify high cpu on interrupt gpe17 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2073538/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
