Gave up waiting for root device.  Common problems:
  - Boot args (cat /proc/cmdline)
    - Check rootdelay= (did the system wait long enough?)
    - Check root= (did the system wait for the right device?)
  - Missing modules (cat /proc/modules; ls /dev)
ALERT!  /dev/sdb4 does not exist.  Dropping to a shell!

Enter 'help' for a list of built-in commands.

/bin/sh: can't access tty; job control turned off
(initramfs) cat /proc/partitions

So this looks easy to fix.
