I installed a small program and that triggered pacman to update the whole system including the kernel. During this process, I realized kernel updates could be handled better:

Kernel updates delete the old modules and so the newly installed modules don't match the running kernel. The running kernel can't now load any further modules. I believe modules should never be deleted by the system (or at least in a much smarter way).

This becomes quite annoying. How do you guys work around this issue?

I can't even insmod a new module with the right path to it  in the old, running, kernel as it refuses to load modules from another kernel version.

Well… a new kernel means you gotta reboot to remain up to date – probably a good way to nudge you in the right direction with regards to having things as recent as possible no matter what

Quote:More seriously, though: You can either downgrade the kernel again until you've loaded the modules you need (if this doesn't happen too often), or see if one of the pre-made solutions work for you, like: https://aur.archlinux.org/packages/kernel-modules-hook (haven't tested that one, no guarantees for anything).

Quote:On servers, I like only allowing pre-signed modules in my precious kernels anyway – this would probably make this all more hellish. I should fiddle around with that on a desktop Arch someday, just for shits and giggles

if you have skills in this area please feel welcome to fix this!

I found it's fixed in the code commit of tsys on sleep issue released yesterday and suspend/resume working nicely now.

It's still cost 30% battery during the sleep of one night.

i rebuilt a 5.5 kernel on debian sid arm64 and can confirm suspend works *better*. for instance, power connection doesn't wake. will test suspend + battery tonight.

There is a new Kernel Released 5.5.0-3.1 which have a better suspend. I have tested 9hrs sleep time with only 1% drain.

Please Update and let me know your feedback.

Thanks.

Pacman says that I have that Kernel installed:

Code:

core/linux-pinebookpro 5.5.0-3.1 [installed]

Are there any extra steps we have to do or updating it through pacman takes care of everything?

Thanks for all your work!

Please report back your results. As our Kernel dev have done some power test at hardware level to measure power consumption while on suspend and it is the lowest as compared to any x86_64 laptop. 

I will do another test tonight and report back.
Thanks.
