can't mount rootfs cause no block devices were detected cause block  
device driver isn't in the kernel or your drives died.

missing one: CONFIG_BLK_DEV_SD. The kernel can't talk to scsi block  
devices. Try enabling the scsi block device driver in the kernel and  
trying again.

If the kernel doesn't find block devices attached to your scsi  
drivers that means the drives are dead or you didn't load the block  
device driver.
