#### Why I did it When using ```sonic-install set-default``` to switch the image from 202012 to 202205. The system will be stuck at loading kernel while reboot. #### How I did it The issue is caused by the kernal size related setting in uboot environment is smaller in the 202012 branch while they are larger in 202205 branch. The "sonic-installer set-default" just changes the boot_next variable. To fix this issue, we sync up the 202012 branch kernel related setting with the 202205 branch. This PR is only applicable to 202012 branch. #### How to verify it 1) Install the latest 202205 image .89 or latest and reboot 2) Install the 202012 image which contains this fix and reboot 3) using "sonic-installer set-default 202205 image and reboot 4) system should start without any issue. #### Ensure to add label/tag for the feature raised. example - PR#2174 under sonic-utilities repo. where, Generic Config and Update feature has been labelled as GCU. |
