Hi Alex, thank you for taking the time to open this ticket. I am glad that 6.8.0-39 fixes the issue for your.
Unfortunately, there is not enough info for us to determine the root cause of this issue. You can refer to the changelog for the noble kernel to see a list of changes that where included between the failing kernel and the working kernel. Here is a link to the changelog for the latest noble (6.8.0-44.44) kernel: https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/noble/tree/debian.master/changelog?h=master-next It should contain all of the changes in the different kernel versions. It appears that ** Changed in: linux (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2076216 Title: Ubuntu 24.04 LTS kernel 6.8.0-35 fails to boot up and get stuck at efi stub measured initrd data into pcr 9 Status in linux package in Ubuntu: Invalid Bug description: From our observation this issue is specific to certain server platform on which we found 6.8.0-35/36 exhibits the same failure symptom, seems like 6.8.0-39 works. On other server platforms 6.8.0-35/36/39 all boot up fine. We'd like to understand the root cause so we can know if the problem lies in specific server platform or in 6.8.0-35/36 kernel. Please refer to the screenshot for the exact screen where the system gets stuck indefinitely.
