Title:
Battery drain during sleep. System suspended before kernel suspends
all tasks
Status in linux package in Ubuntu:
Expired
Bug description:
Description: Ubuntu 18.04.2 LTS
Release: 18.04
Expected behaviour:
No battery drain during suspend.
Ubuntu 18.04 running on a Thinkpad L390 has battery drain during
suspend (~10% in 5 hours) in. I excluded wake ups during sleep and
checking the logs I have realized that the kernel suspends too fast,
before the full system is put to sleep.
Here are the syslogs after initiating the suspend mode:
Apr 19 11:59:53 ThinkPad-L390 systemd[1]: Starting TLP suspend/resume...
Apr 19 11:59:53 ThinkPad-L390 systemd[1]: Started TLP suspend/resume.

Note: Between the two syslog extracts are no further events.
As it can be seen in the logs, the CPU cores are only put the sleep after the
suspend is finished, which leads to the messages like:

should not be sleeping
Apr 19 12:37:50 ThinkPad-L390 kernel: [15460.429898] CPU1 is up
