Title:
Kernel panic with AWS 4.4.0-1053 / 4.4.0-1015 (Trusty)
Status in linux package in Ubuntu:
Triaged
Bug description:
This is a POTENTIAL REGRESSION.
This issue only occurs on one of the AWS testing instance "c3.large"
Reproduce rate: 100% (All jenkins deployment job failed with this
instance)
Steps:
1. Deploy this instance with AWS kernel (4.4.0-1052)
2. Enable -proposed, upgrade it and reboot.
Result:
* System can boot with 4.4.0-1052, but it won't be accessible after
rebooting for 4.4.0-1053, from "aws ec2 get-console-output" command indicates
it hang with kernel panic issue on boot. It looks like the intel-microcode is
causing this issue.
Output from the command: https://pastebin.ubuntu.com/p/3JvWNk5CTs/
(it's a bit difficult to get full output, the instance will keep
rebooting itself)
