Comment 0 for bug 1721856

The standby ends after seconds and the laptop resumes like it'd wake up from standby. I didn't use standby for a long time (months or years) and can't even estimate when it worked for the last time.

This issue is fixed in 4.14-rc3 mainline kernel! I'm willing to do git bisect work if you confirm me that this makes sense.
