Title:
Latest linux-generic package (kernel 4.15.0-136) doesn't work on
HyperV Gen2 VM
Status in linux package in Ubuntu:
Incomplete
Bug description:
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.
