Make sure that "deep" suspend is used instead of `s2idle` suspend (`echo deep | sudo tee /sys/power/mem_sleep`). This is always the case when the "Power->Suspend State" is set to "Linux" instead of "Windows 10" in the BIOS. 2. Trigger suspend, e.g. with GUI or `systemctl suspend -i` 3. System suspends successfully. Power light starts fading in and out, as it should. 4. Wake up the system. This is only possible with the power button instead of keys, which is a difference from `s2idle` suspends. 5. Unlock lock screen 6. Notice that the system will behave buggy/abnormal as the filesystem is remounted as read-only. Shortly after resuming, applications will start to crash or show nonsensical output. Expected behavior: (From step 4) System wakes up and can be used normally. The main filesystem should of course be writable.
