Hi Evan, The kernel team have built all of the kernels for this SRU cycle, and have placed them into -proposed for verification.
We now need to do some thorough testing and make sure that Raid10 arrays function with good performance, ensure data integrity and make sure we won't be introducing any regressions when these kernels are released in two weeks time. I would really appreciate it if you could help test and verify these kernels function as intended. Instructions to Install: 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 For 21.04 / Hirsute: 3) sudo apt install linux-image-5.11.0-20-generic linux-modules-5.11.0-20-generic \ linux-modules-extra-5.11.0-20-generic linux-headers-5.11.0-20-generic For 20.10 / Groovy: 3) sudo apt install linux-image-5.8.0-56-generic linux-modules-5.8.0-56-generic \ linux-modules-extra-5.8.0-56-generic linux-headers-5.8.0-56-generic For 20.04 / Focal: 3) sudo apt install linux-image-5.4.0-75-generic linux-modules-5.4.0-75-generic \ linux-modules-extra-5.4.0-75-generic linux-headers-5.4.0-75-generic For 18.04 / Bionic: For the 5.4 Bionic HWE Kernel: 3) sudo apt install linux-image-5.4.0-75-generic linux-modules-5.4.0-75-generic \ linux-modules-extra-5.4.0-75-generic linux-headers-5.4.0-75-generic For the 4.15 Bionic GA Kernel: 3) sudo apt install linux-image-4.15.0-145-generic linux-modules-4.15.0-145-generic \ linux-modules-extra-4.15.0-145-generic linux-headers-4.15.0-145-generic 4) sudo reboot 5) uname -rv You may need to modify your grub configuration to boot the correct kernel. If you need help, read these instructions: https://paste.ubuntu.com/p/XrTzWPPnWJ/ I am running the -proposed kernel on my cloud instance with my /home directory on a Raid10 array made up of 4x NVMe devices, and things are looking okay. I will be performing my detailed regression testing against these kernels tomorrow, and I will write back with the results then. Please help test these kernels in -proposed, and let me know how they go.
