Public bug reported: On Ubuntu 18.04 LTS 1&2 (so far tested), either when deploying a new VM (which pulls the latest linux-generic) or rebooting a VM (which updated the linux-generic under the cover which installs 4.15.0-136) will prevent the VM to boot.
After reboot, will get stuck on /dev/sdX: clean, x / y files, k / m blocks. Using grub, selecting an older kernel, allow the VM to book without any issues. I manually installed kernel 4.15.0-135, however the issue doesn't repro. Finally I've verified that this repro on both Server 2016 and Server 2019 versions of Windows... Output of /proc/version_signature (both on Server 2016/2019) Ubuntu 4.15.0-29.31-generic 4.15.18 lspci -vnvn reported empty on this VM. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Attachment added: "output.png" https://bugs.launchpad.net/bugs/1917958/+attachment/5473666/+files/output.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1917958 Title: Latest linux-generic package (kernel 4.15.0-136) doesn't work on HyperV Gen2 VM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1917958/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
