--- Comment #70 from Miroslav Pavleski (miroslav@pavleski.net) ---
😅 Um.. yeah, I was using modified ACPI to enable S3. I did that because s2idle
was freezing either on suspend or on resume in most of the cases.

The modification was done as documented in **S3_Instructions.md** in the
uploaded **2025.02.17_Report_Miroslav.zip** .


Now for testing, I've removed the **acpi-cpufreq=disable** and removed the ACPI
modification.

First attempt of sleeping, to s2idle - System frooze (never turned fans off,
never got blinking power led)
Second attempt - same result
Third attempt - It went sleeping (fans off, led blinking). Did not resume, got
stuck.
Fourth attempt - It supsended and resumed ok.
Fifth attempt - On the same boot as the fourth, froze the system again, never
reaching suspend.

In all cases where it got stuck I had to power off using holding the power
button.

I'm attaching the part the first two attempts journals.

Also I'm attaching the results (**s2idle_report-2025-02-17.txt**) of running
**amd_s2idle.py** with unmodified ACPI, so with s2idle sleep.
