I can confirm I have the same problem with Ubuntu 25.04 + kernel 6.17.9.
I’ll test 6.18.0 and report.
Word of warning - you’ll want this on 6.18
@Mario_Limonciello do you mean it is in 6.18 and that’s why I need 6.18 or I need to patch 6.18?
It was a regression in 6.18. it will be in 6.18.y but timing. So just add it when you do your build.
@Mario_Limonciello do you think that upgrading Linux to 6.18 could solve the problem? It feels a bit strange to me as @Lukew4lker is having a similar problem on Windows.
Is there anything that I could do to help troubleshoot the issue?
Did you by chance turn off pluton in BIOS? That will break suspend.
You can run amd-s2idle from amd-debug-tools · PyPI to help triage.
Happy to report vanilla 6.18 works without issues.
IDK what the patch is supposed to prevent (link is 503 right now so I can’t check), but I haven’t had any problem so far: desktop now suspends and resumes fine.
