The kernel team have built the next kernel update, and they have placed it in -proposed for verification.
The versions are 4.15.0-125-generic for Bionic, and 5.4.0-55-generic for Focal.
Can you please schedule a maintenance window for the Launchpad git server, to install the new kernel in -proposed, and reboot into it, so we can verify that it fixes the problem.
Instructions to install (On a Bionic system):
Enable -proposed by running the following command to make a new sources.list.d entry:
1) cat << EOF | sudo tee /etc/apt/sources.list.d/ubuntu-bionic-proposed.list
# Enable Ubuntu proposed archive
deb http://archive.ubuntu.com/ubuntu/ bionic-proposed main
EOF
2) sudo apt update
3) sudo apt install linux-image-4.15.0-125-generic linux-modules-4.15.0-125-generic \
linux-modules-extra-4.15.0-125-generic linux-headers-4.15.0-125-generic linux-headers-4.15.0-125
4) sudo reboot
5) uname -rv
4.15.0-125-generic #128-Ubuntu SMP Mon Nov 9 20:51:00 UTC 2020
6) sudo rm /etc/apt/sources.list.d/ubuntu-bionic-proposed.list
7) sudo apt update
If you get a different uname, you may need to adjust your grub configuration to boot into the correct kernel. Also, since this is a production machine, make sure you remove the -proposed software source once you have installed the kernel.
Let me know how this kernel performs, and if everything seems fine after a week we will mark the Launchpad bug as verified. The timeline for release to -updates is still set for the 30th of November, give or take a few days if any CVEs turn up.
I believe this kernel should be live-patchable, although this may not be the case if the kernel is respun before release. Hopefully you will only have to schedule the maintenance window just the once.
