Linux fails to wake Joule from S3 suspend with rtcwake. Reason: ACPI bug
It looks like ACPI is lacking support for RTC wake or wake via a power button press. From dmesg during boot: ACPI Error: Could not enable PowerButton event (20160930/evxfevnt-212) ACPI Error: Could not enable RealTimeClock event (20160422/evxfevnt-212) This is a known issue, being investigated by the BIOS/ACPI team.
The bug has been worked around in our CI for now with a dedicated piece of HW from Imre, but the bug is still present and should be fixed upstream! Imre, can you put a dependency for this bug on the bug filed to the core team?
Imre - please note comment 2.
