--- Comment #15 from kolAflash (kolAflash@kolahilft.de) ---
I booted the Kubuntu-22.10 beta which comes with linux-5.19 (ran the live image
from USB storage). And the power consumption was at about 2 % per hour. The
kernel is pretty much the same to what I'm using with openSUSE, so in some way
the userspace must make a difference. At least in the way the userspace
configures the kernel via sysfs.

Then I went back to my openSUSE-15.4 system, running the linux-6.0-rc6 kernel I
compiled. And I disabled all sysfs wakeup triggers from userspace.
  find /sys/devices/ -type f -name wakeup -exec bash -c 'echo disabled > "{}"'
\;
And indeed, power usage went down to 2 % per hour! :-)
So should I open a bug for s2idle in openSUSE instead!?




I also tried other Linux distros a kernel >= 5.19. But I couldn't get the
s2idle power usage significantly below 2 % per hour. So S3 is still about 4
times better with around 0.5 % battery usage per hour.

Tomorrow I'm planning to do the debugging steps described by Mario in comment
#14.
So maybe with that the consumption can be brought further down for s2idle.

But I also still the idea of using S3 (especially because of the very low power
consumption).
---> So I'd still like to see a fix for the commit initially mentioned. Or
maybe not a fix, but a kernel command line option to disable that behavior.
