Status in linux package in Ubuntu:
Incomplete
Status in linux source package in Hirsute:
Won't Fix
Bug description:
This was caught while testing a few runs in the google cloud.
Steps to reproduce:
1.) deploy 21.04 in the cloud (n1-standard-1 instance type)
2.) install 5.10.0-3.4 from the canonical-kernel-team bootstrap ppa
2a.) sudo add-apt-repository ppa:canonical-kernel-team/bootstrap
3.) sudo apt install linux-generic-wip
4.) update grub to boot the generic kernel as the default kernel will be
-gcp, (use attached script comment#4) ./script.sh generic
5.) reboot and monitor console logs
Full startup logs attached:
looks to be grub related, I have not looked into this any further.
