Bug Description
== SRU justfication, BIONIC (and XENIAL too) ==
[ update - doing the SRU for XENIAL too, Fri, 10th Aug 2018 ]
While performing Hibernate stress tests on a device with 18.04 server installed, we got some failures with FWTS and reported them in lp:1769809.
Even though some of these original failures are due to a bug in Checkbox, some others are due to the fact that the Bionic kernel 4.15 has a parameter "pm_debug_messages" that needs to be enabled.
If you run the stress tests on this device, you will end up with 4 PASS and 2 FAIL. But if you run this command before running the stress tests:
$ echo 1 | sudo tee -a /sys/power/
then all tests are marked as PASSED.
(see comment #9 in the bug above for more information)
It looks like this is something that should be taked into account by FWTS. (but I might be wrong!)
Thanks!
== Fix ==
Upstream commits:
lib: fwts_set: fix API for fwts_set, add fwts_set_int
lib: add small helpers top get/set
acpi: s3: force enable /sys/power/
acpi: s4: also check for file based swap files
acpi: s4: force enable /sys/power/
acpi: s3power: force enable /sys/power/
== Regression Potential ==
Minimal, this fix enables a setting in /sys/power/

@colin,
Do you think this should be fixed in fwts or in bionic kernel?
