Hi, by "failed to boot", could you give some more details about what happened? Could you try to edit kernel boot parameters at grub, remove "quiet splash", and add:
ignore_loglevel debug initcall_debug log_buf_len=32M earlycon=efifb And attach the screenshot and/or dmesg of that 5.3.0-40-generic kernel boot? -- 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/1866879 Title: Failure to boot on linux-image-5.3.0-40-generic Status in linux package in Ubuntu: Confirmed Bug description: I installed Ubuntu on the laptop, rebooted and everything was fine. I did an upgrade to all packages and found that when I rebooted, it fails to load. I found out that a workaround is to select linux- image-5.3.0-18-generic in grub which leads me to think that the issue is related to the upgrade of the linux-image 5.3.0 package. To be clear, linux-image-5.3.0-18-generic works but linux- image-5.3.0-40-generic does not.
