It sounds like your kernels aren't assembling the RAID device on boot, 
which *might* be related to the above bug if one of the devices is 
broken.  It's hard to tell from your description.  You mentioned that 
the rescue kernel boots, but I wonder if the array is degraded at that 
point.

Otherwise, you might remove "rhgb" and "quiet" from the kernel boot 
parameters and see if there's any useful information printed to the 
console while booting a recent kernel.
