    Upgrade to 15.04 kernel 3.19 goes to busybox on boot, 3.16 boots fine

    I have full disk encryption. On boot with 3.19 boot goes into busybox, boot with 3.16 starts fine.

    dmesg from busybox gives an error like
    Code:
    EXT4-fs: couldn't mount as ext3 due to feature incompatibilities
    fstab
    Code:
    # <file system> <mount point>   <type>  <options>       <dump>  <pass>/dev/mapper/ubuntu--vg-root /               ext4    defaults,errors=remount-ro 0       1
    # /boot was on /dev/sda1 during installation
