Resumes fails on AMD Ryzen 5 4500U with GPU Renoir (Acer Swift 3 SF314-42-R2UX)

As mentioned here: #1230 (comment 902370) I suspend isn't working on my machine either.

CPU: AMD Ryzen 5 4500U with Radeon Graphics (6) @ 2.375GHz
GPU: AMD ATI 03:00.0 Renoir
Model: Acer Swift 3 (SF314-42-R2UX)
OS: Ubuntu 21.04

I tried all patches mentioned in #1230 (closed) on Kernel 5.14 but with little success: Some times the machine will wake after first suspend but not always and at least I usually can SSH into my machine.

I was hoping for Kernel 5.15 and tried v5.15-rc2 but unfortunately the situation worsened: My machine wont wake up at all after suspend.

Trying to get on top off recent developments I found it quite hard to grasp, which patches on which kernel version I should try to solve the issue.

• Could somebody please summarize for me, what to try?

Here are some logs:
