Running this tool hangs the system

[project-administrator]

I ran the following command:

./s0ix-selftest-tool.sh -s

The system suspended into s2idle. After 5 seconds or so it wakes up and shows messages on the console about "read-error swap device" and "buffer IO error on device" of my boot partition. From this moment the system is frozen and I have to hold the power button for a few seconds to turn it off.
Logs of the s0ix:

$ cat 20221017-09-44-s0ix-output.log

From your description, your system have issue to suspend to idle(s2idle).
Suggestion, trying to disable all the ACPI wakeup device:
cat /proc/acpi/wakeup
echo XHC > /proc/acpi/wakeup

Then try commands:
echo 0 > /sys/class/rtc/rtc0/wakealarm
echo +30> /sys/class/rtc/rtc0/wakealarm
echo freeze > /sys/power/state
