I have two AMD-based systems with KaOS installed and neither of them suspend/resume properly.
One is a notebook and the other an all-in-one. They seem to "suspend" okay, but when I strike a key to resume them they seem to try and start back up but never make it. The screen is blank and I have to force reboot (most recently on the AIO, the BIOS reset as a bonus).
The Intel system on the other hand works as expected.
If this is not the right place to report this that's fine. If anyone knows where it should be reported I'll do that.
