Link2sd working fine for me using a G510 with mmcblk1p1 as fat32, p2 as ext4 and p3 as a swap partition.
I have the same problem, phone network is worse than before; lost 2 or more bars where I had 3 or more before.
Link2sd is not working, keps giving the same error during init script creation: "impossible to create the init script - mount: invalid argument. "
Without link2sd this rom is much less usable for me... anyone has a work around?
Have you enabled root? What is your setup?
