Cannot enter supend-to-RAM state on Huawei Matebook X Pro 2024

[amankhoza]

For some reason my machine does not enter deeper levels of suspend such as suspend-to-RAM instead it remains at s2idle. From looking at logs it appears to be an ACPI issue so I'm hoping whether one of the contributors of this repo can help or provide guidance, I'm willing to help test patches etc.

Here's an example of dmesg logs mentioning ACPI errors:
