My hardware is AMD as well, and I was having the same problem of system being frozen on reboot.

I meant resume.

I have upgraded my LibreELEC system to an AMD one (CPU/motherboard/video card). After the upgrade LibreELEC was consistently freezing on resuming from sleep state S3. However, this did not happen when I booted other Linux distros in the same system. After spending a lot of time troubleshooting this issue (including playing with firmware settings and kernel parameters) I finally found out the culprit:

LibreELEC kernel is built with this patch that disables async suspend/resume by default. This can be verified at runtime via /sys/power/pm_async.

# cat /sys/power/pm_async
0

It is possible to re-enable it:

# echo 1 > /sys/power/pm_async
# cat /sys/power/pm_async
1

After this change, my system consistently resumes from suspend. I have not experienced a single freeze with it enabled.

To make this change persistent, I created this file:

w /sys/power/pm_async - - - - 1

Posting here hoping that this recipe will prove useful to others here.

My hardware is AMD as well, and I was having the same problem of system being frozen on reboot. Curiously, other Linux distros in the same machine didn't have it. After a lot of experimentation, I found out that this fixed it for me:

echo 1 > /sys/power/pm_async

The value `1 is the Linux default, but LibreELEC has a patch that disables it: https://github.com/LibreELEC/Libr…y-default.patch

To make this change persistent create this file:

w /sys/power/pm_async - - - - 1

FYI: the link to download the Legacy image is erroneously pointing to the non-legacy version:
