enable system suspend

revert !279 (merged) and add the workaround script for temporary kernel bugs we haven't yet fixed.

from my preliminary tests (with looking at system consumption on shipmode or looking at charge_now after a while), I'd say suspend can save roughly 40% of power consumption compared to a completely idle display-off, no modem, but wifi connected device. I see ~0,13 A during suspend.

marked this merge request as ready

the kernel is ready for testing as of https://source.puri.sm/Librem5/linux-next/-/merge_requests/541 so please allow it via systemd.

Suspend is working here most of the time, thanks! I was triggering it via systemctl suspend and twice after entering suspend the phone wouldn't wake up after pressing power key. Below journalctl after triggering suspend.

• Please adjust commit messages when reverting to explain

  • why the commit was reverted
  • what is broken / unbroken by this

  The current one just says This reverts commit 697a7420.

• Don't you need a Breaks for kernels not supporting this?

• Can we have a mention (or link) to the status of wwan, calls, wifi, etc since suspend related MRs were linked around in several public places (which is good) so expectations are set correctly?

Compare with previous version

the required kernel migrates in a day or 2. IMO this is ready as this will allow people to very easily test and allow us to add a testcase.

I want to avoid that any future change breaks what we have right now. And while it works for me reasonably fine, this enables us to find any remaining issue people come up with.

I've been running with this change for a few days and the systemd logic works fine.

The autopkgtest fails for other reasons:

gnome-calls : Breaks: phosh (< 0.14.1-2~) but 0.14.1-1pureos1 is to be installed

/cc @evangelos.tzaras since this also means calls can't migrate without phosh.
