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!
