Confirming for both 4.15.0-44 and 4.15.0-45 on Windows Server 2012 Hyper-V. For now I've forced GRUB to boot 4.15.0-43.
The guest is Ubuntu Server 18.04.1. FWIW, the VM has 2 virtual cores and dynamically-allocated memory of up to 6144 MB. I'm only able to view the boot process in Hyper-V's "Virtual Machine Connection" console, which has no scroll buffer. When boot failure occurs, I can see the last few lines of an error trace in the console, but I've been unable to capture the full trace. No information regarding the boot ends up in the system logs--i.e., journalctl doesn't recognize the failed boot attempts at all. -- 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/1814069 Title: kernel linux-image-4.15.0-44 not booting on Hyperv Server 2008R2 Status in linux package in Ubuntu: Confirmed Bug description: Ubuntu stuck on booting on HyperV Server 2008R2.
