[CoLoCo] RAID killed my box - aaaagh!

Reason #5234 why Linux rocks - even though my main install isn't working, I
just booted an older version on a spare hard drive. I have my computer back,
all my data is accessible and I can trouble shoot from here while continuing
to do whatever I want or need to.

Anyway, I'm booted into a regular install (non-raid). I have installed mdadm
and can see and mount my raid volumes. /proc/mdstat gives

Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4]
[raid10]
md1 : active raid1 sda2[0] sdb2[1]
      19534976 blocks [2/2] [UU]

md0 : active raid1 sda1[0] sdb1[1]
      291017344 blocks [2/2] [UU]

It would seem that there is nothing especially wrong with the drives. I just
can't boot. In verbose mode I can see that md0 and md1 are being stopped.
Why? I'm sure that is why I can't boot. If the drives are stopped then how
can all the boot files be accessed. They are not stopped to begin with
because grub wouldn't even load nor would boot as far as it does. Does this
make sense to anyone? I've tried running update-initramfs and reinstalling
udev (ideas I found by googling). Nothing worked yet.

Thanks,
-jim
