MAAS supplied GRUB affected with LP# 1947046

[Alan Baghumian]

The grubaa64.efi supplied with MAAS seems to be affected with LP:1947046 causing boot issues with the recent 5.15 as well as HWE kernels.

Tested and encountered this issue while experimenting with commissioning Raspberry Pi4B on MAAS. Also tested with Impish (5.13) and Groovy (5.8) kernels and they are functioning correctly.

Would be great if we can patch this issue.

Thank you.

Note: The screenshot is showing the same issue when booting from local disk using GRUB 2.04.

Please let me know if you'd like me to perform any kind of testing etc.

It seems that we need to promote a new candidate for the bootloader

Once this will be out, we can get the new bootloader candidate

Hello,

I am seeing same issue with latest Jammy kernel and grub2-arm64 from images.maas.io

[Jerzy Husakowski (jhusakowski)]

@Alan - Could you please test with the candidate stream? Once it's confirmed that the appropriate fix landed there and works for you, we can promote a new image. Here's how to change the stream: https://maas.io/docs/how-use-standard-images#heading--changing-the-stream

[Alan Baghumian (alanbach)]

Hi @Jerzy! I just downloaded a copy from the candidate stream and passed it on to our client to test. I will keep you posted.

[Alan Baghumian (alanbach)]

Hi @Jerzy! Our client confirmed the Candidate version worked on their ARM servers. Just wanted to let you know to proceed to the next step.

[Jerzy Husakowski (jhusakowski)]

This will be fixed in maas-images, no changes in MAAS required.
