Subject: 2.6.0-test1-bk2 ate my root raid

I tested 2.6.0-test1-bk2 out, and it wouldn't boot using 
my devfs name. No real problem there, as I've seen the workaround--
use the huge ugly devfs name (or hex'ed numbers)--I've got a backup root
partition (I've got to learn to type one of these days if I play with
root). Boot using the backup partition, 
"2.6.0-test1-bk2 root=/dev/hdc1 init=/bin/bash" and notice that 
the new kernel doesn't see my promise controler (odd that, half
of the raid is on that "lost" drive"). 

Boot back into 2.4.21; I get a quick kernel panic (no root)
but can't tell why as once you've panic'ed you can't scroll up. I've
got a Knoppix cd, so all will be well. Boot that, and load the md 
modules and got the following, and here I'm a bit stumped :"
