dmesg CFL-1
When I send the CFL to S3, S4 and Freeze, DUT is not able to get back from
these states with latest configuration.
When I run these tests without firmware and try to get back from any of these
states, I get video from the monitors but DUT still without response.
There is a physical swap partition available for these test
Steps:
1.-With a physical swap partition available run the following commands:
# echo mem> /sys/power/state
# echo disk > /sys/power/state
# echo freeze > /sys/power/state
2.- Check that DUT is not able to get back from any of these states
This looks like a regression, due to kernel 4.13-rc7-428ed2734 didn't present
this kind of issues.
Attached kernel.log, dmesg.log and configuration of two different CFL where
these tests were performed.
