It sounds to me like grub is doing its job.  However, there
is some ambiguity about which disk is sda.  That's not unexpected
in cases like this... you can't count on the enumeration provided
by the storage drivers.  Can you change the kernel command line
so that it uses a UUID or a label to identify the intended root
partition?
