[Bug] - Hibernate stopped working on 2023.9.20251208

[p24-max]

Describe the bug
AL2023 cannot be hibernated anymore with version 2023.9.20251208. I tested it with a new instance using ami-097e0f4a93b046e1a and ami-089dc6fe381a457ca with T4G.micro, both not working.

To Reproduce
Steps to reproduce the behavior:

1. Launch new instance based on ami-097e0f4a93b046e1a with t4g.micro (set Stop - Hibernate behavior = Enabled)
2. Once instance is up, hibernate from EC2-console
3. Instance is now stuck in "Stopping" state

Expected behavior
Instance hibernates successfully like with previous versions of AL2023.

Additional context
I tested same with ami-0a617b714486fa084 (al2023-ami-2023.9.20251117.1-kernel-6.12-arm64), there it worked as expected.
