Kernel log for hardware

I get the below two kernel errors in log when I resume from hibernate and while using DRI probably. I have latest amdgpu non-free firmware and mesa v24 installed.

amdgpu 0000:04:00.0: amdgpu: failed to write reg 28b4 wait reg 28c6
amdgpu 0000:04:00.0: amdgpu: failed to write reg 1a6f4 wait reg 1a706

I have the following kernel parameter set to try and mitigate the above issue but still the issue happens.

iommu=soft

The above issue does not occur during s2idle sleep/wakeup but only after resuming from hibernate.

Attaching some kernel log if that would be of any help.

I found this issue with kernel version 6.6.x and 6.10.x

Please first test 6.11.7 and if it's still reproducible, report here: https://gitlab.freedesktop.org/drm/amd/-/issues
