Due to the new asynchronous probing of mmc controllers, the mmcblock device numbers likely have changed, as seen here:
[ 1.652275] mmc1: new high speed SDHC card at address 0001 [ 1.652568] hub 1-1:1.0: USB hub found [ 1.658587] mmcblk1: mmc1:0001 EB1QT 29.8 GiB [ 1.661777] hub 1-1:1.0: 4 ports detected [ 1.670263] mmcblk1: p1
You should change your root device specification to use PARTUUID, instead of hardcoding the index.
