AceLan Kao,
First, I added "noble-proposed" to /etc/apt/sources.list.d/ubuntu.sources:
$ sudo sed -i '/^Suites/ s/$/ noble-proposed/'
/etc/apt/sources.list.d/ubuntu.sources
then I ran, apt update:
$ sudo apt update
Then I was able to install the 6.8.0-40 kernel:
$ sudo apt install linux-image-generic/noble-proposed
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Selected version '6.8.0-40.40' (Ubuntu:24.04/noble-proposed [amd64]) for
'linux-image-generic'
The following additional packages will be installed:
linux-image-6.8.0-40-generic linux-modules-6.8.0-40-generic
linux-modules-extra-6.8.0-40-generic
Suggested packages:
fdutils linux-tools linux-headers-6.8.0-40-generic
The following NEW packages will be installed:
linux-image-6.8.0-40-generic linux-image-generic
linux-modules-6.8.0-40-generic linux-modules-extra-6.8.0-40-generic
0 upgraded, 4 newly installed, 0 to remove and 97 not upgraded.
Need to get 167 MB of archives.
After this operation, 166 MB of additional disk space will be used.
Do you want to continue? [Y/n]
Then I rebooted:
$ sudo reboot
$ uname -a
Linux victus 6.8.0-40-generic #40-Ubuntu SMP PREEMPT_DYNAMIC Fri Jul 5
10:34:03 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux
there was 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:978 [typec_ucsi]ucsi_connector_change =p "Early

drivers/usb/typec/ucsi/ucsi.c:1626 [typec_ucsi]ucsi_register =p "Registered

# modprobe ucsi_acpi
# dmesg|egrep ucsi

[ 147.900400] ucsi_acpi USBC000:00: error -ETIMEDOUT: PPM init failed
next attempt will be with v6.11-rc1 as you have suggested.

Title:
kacpi_notify high cpu on interrupt gpe17
Status in linux package in Ubuntu:
In Progress
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.
