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

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
connector change event\n"
drivers/usb/typec/ucsi/ucsi.c:1626 [typec_ucsi]ucsi_register =p "Registered
UCSI interface with version %x.%x.%x"
# modprobe ucsi_acpi
# dmesg|egrep ucsi
[ 142.839586] ucsi_acpi USBC000:00: Registered UCSI interface with version

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