It seems they are included in 6.8.0-53-generic and 6.11.0-17-generic.

These kernels are currently in -proposed.

Justus, would you like to try the noble -proposed kernel out and let me know
if it fixes the issue?

Instructions to Install (On a noble or oracular system):
1) cat << EOF | sudo tee /etc/apt/sources.list.d/ubuntu-$(lsb_release 
-cs)-proposed.list
# Enable Ubuntu proposed archive
deb http://archive.ubuntu.com/ubuntu/ $(lsb_release -cs)-proposed main universe
EOF
2) sudo apt update
On Noble:
3) sudo apt install linux-image-6.8.0-53-generic linux-modules-6.8.0-53-generic 
linux-modules-extra-6.8.0-53-generic linux-headers-6.8.0-53-generic
On oracular:
3) sudo apt install linux-image-6.11.0-17-generic 
linux-modules-6.11.0-17-generic linux-modules-extra-6.11.0-17-generic 
linux-headers-6.11.0-17-generic
4) sudo reboot
5) uname -rv
6.8.0-53-generic #55-Ubuntu SMP PREEMPT_DYNAMIC Fri Jan 17 15:37:52 UTC 2025
or
6.11.0-17-generic #17-Ubuntu SMP PREEMPT_DYNAMIC Thu Jan 16 23:58:35 UTC 2025

These Kernels are a part of the 2025.01.13 SRU cycle. We are expecting a release
to -updates likely the week of 10th of Feb, or maybe a week later, as I hear
this cycle is delayed a week.

Thanks,
Matthew
