oh, yeah, that's a common one too.

It can be useful (I've done it anyway) to set up an initrd with a few
handy tools, and drop into a shell while in initrd, and see what's up.
Do the bringup steps by hand, in other words. It can be illuminating.
Makes for a big initrd, but hey ... it's for debugging. Although I've
run  cluster nodes with nothing but an initrd.
