Public bug reported: 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) ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Description changed: This is a POTENTIAL REGRESSION. - This issue only occur on one of AWS testing instance "" + This issue only occur on one of the AWS testing instance "c3.large" Reproduce rate: 100% (All jenkins deployment job failed with this instance) Steps: - 1.
