Description Tomi Sarvela 2017-02-20 16:17:38 UTC
Linux fails to wake Joule from S3 suspend with rtcwake. Reason: ACPI bug
Comment 1 Imre Deak 2017-02-20 19:09:01 UTC
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.
Comment 2 Martin Peres 2017-03-06 11:18:07 UTC
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?
Comment 3 Jari Tahvanainen 2017-04-11 11:30:07 UTC
Imre - please note comment 2.
