apple/macbook-pro/12-1: won't resume after hibernation

ivankovnatsky commented 3 years ago

description: systemctl hibernate -- works fine, though when resuming it fails to get into the system, and the system reboots by itself.

kernel: Linux mac 5.4.78 #1-NixOS SMP Wed Nov 18 18:20:34 UTC 2020 x86_64 GNU/Linux

using:

  systemd.sleep.extraConfig = ''
    HibernateMode=shutdown
  '';

ram/swap:

❯ free -m

Just to clarify. The swap is big enough. Is there disk encryption used?

added some description, but you're right, that's all upstream issues, same as my another issue here, concerning wireless.

apparently there are lots of issues with specifically brcmfmac driver (or the hardware itself).

pretty old bug, but i guess still relevant:

https://bugzilla.kernel.org/show_bug.cgi?id=101681#c116

because i had success resuming after hibernation doing: rmmod brcmfmac && systemctl hibernate.

We could try to automate this with systemd suspend modules: https://gist.github.com/mauron85/f764c88d2dc47af157487a7a318dd35b
