Have you tried "rootdelay=5"?  That has helped me in the past.  That option
makes the kernel wait 5 seconds for the root device.  If that helps then try a
smaller number so your boot time won't be overly long.  Also add "noquiet" so
you will see all the kernel messages as it boots. 

Just add those 2 kernel options to whatever is already in GRUB_CMDLINE_LINUX= in
/etc/default/grub.  Quiet may already be there so just add the no in front. 
Then run update-grub so grub can update /boot/grub/grub.cfg file.
