Bug Description
This is an odd one, and I'm unsure what is causing it.
I have a thinkpad T480s with an i7-8550U that used to sleep and resume well in jammy and lunar.
I have now reinstalled mantic from scratch and I am unable to resume from deep sleep.
What works and what doesn't:
* mantic live USB installer + kernel 6.5.0.9 + deep sleep → WORKS
* mantic installation on nvme w/zfs + kernel 6.5.0.10 + deep sleep → does not resume
* mantic installation on nvme w/zfs + kernel 6.5.0.9 + deep sleep → does not resume
* mantic installation on nvme w/zfs + kernel 6.5.0.10 + s2idle sleep → WORKS
In other words the only differentiator seems to be zfs.
I also have a P14s G4 (Ryzen 7840U) running mantic that sleeps without issue, although only s2idle is available in /sys/power/
