Since I was affected on Ubuntu 19.04 using the generic Kernel (5.0.0-15-generic), I am not sure if "linux-signed-hwe" is the right thing to file this bug against...
I decided to test Mainline 5.1.6 under Ubuntu 19.04, and it's also affected. I have been looking into kernel/power/suspend.c, and if you trace down (as in: follow the code step by step) that suspend.c, it becomes obvious that it's not suspend.c by itself, as it's impossible to be a timing problem purely in there, as suspend.c *does* do things in order. I am beginning to think that systemd might be doing things wrong. Since I could also reproduce this issue with fedora, I will be testing on gentoo without systemd (using openrc) and tell you how this worked out. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1825636 Title: Battery drain during sleep.
