The computer never woke and needed to be hard-rebooted if it was ever allowed to suspend? I ran into this after installing Linux on a MacBook, downgrading the kernel to an old LTS release eventually worked.
Yep. The issue was that the NVMe controller wouldn't wake up properly. Downgrading the kernel wouldn't have helped, as support for that NVMe controller itself had just recently been added.
