IMHO, this means that it can't mount the root partition.
I saw this happen on root partitions that were on SCSI drives, but SCSI
support was not compiled in the kernel, it was a driver.
The kernel could not start and load modules, because the modules were
on this SCSI disk, and there was no SCSI module in the kernel.
I don't know what driver or module you use for the RAID, but I would
compile everything you need for these into the kernel, and if everything
works start modulazing one by one.
