I setup my pxe server to provision jammy beta and got the following kernel panic message after grub stage:

= Steps to Reproduce =
1. Followed this guide to setup the pxe server https:/
1-1. You may use this script to perform the set-up https:/
2. Boot the system via PXE
3. Select Ubuntu at Grub menu
= Expected Result =
The image is loaded to the system locally via PXE, and subiquity is launched
= Actual Result =
Console log simply shows nothing for 10 seconds and then the kernel panic shows up.
= Additional Information =
- If we install via the virtual CD of the server, subiquity could be launched and the installation process completes successfully.
- MAAS could deploy Jammy to the Mt. Jade server as well.
