However if I press ctrl-d to the system continues to boot fine (also will boot fine if I reboot the system)

What does that mean? It only happens sometimes?

Have you check the UUID in fstab against lsblk -f / blkid output?

Re: System drops to emergency shell on mounting btrfs /home subvolume

UUID matches lsblk -f and fstab.
It seems to happen constantly on the first reboot or power on but does not occur if a reboot the system again, as I said the error also resolves itself if I continue booting after the emergency shell. It seems the system does not wait long enough for /home to mount.

Re: System drops to emergency shell on mounting btrfs /home subvolume

Or possibly only when I boot into windows to play a game
