Jeff,

I took a stab at it and got it to boot, but the boot hung around rc.local.
So I rebooted it with init=/bin/sh and manipulated it a bit by hand.

I have three drives in the machine:

ata1: sda: spare disk that I test Andi's RAID1 theory.
ata3: sdb: first drive of the system RAID1 pair
ata4: sdc: second drive of the system RAID1 pair.

I can write to ata1 no problem; I did the following:

cd /
mount /dev/sda1 /mnt
cp -axv . /mnt/root
sync

and that all worked.

Can't seem to write to ata4:

ata4: command 0x35 timeout, stat 0x50
ata4: command 0x35 timeout, stat 0x50
ata4: command 0x35 timeout, stat 0x50

/proc/mdstat shows:

Personalities : [raid1]
md2 : active raid1 sdc2[1] sdb2[0]
1052160 blocks [2/2] [UU]
resync=DELAYED

md3 : active raid1 sdc3[1] sdb3[0]
586304 blocks [2/2] [UU]

md5 : active raid1 sdc5[1] sdb5[0]
70838464 blocks [2/2] [UU]
[>....................] resync = 0.0% (64768/70838464) finish=127224.1min speed=9K/sec

md1 : active raid1 sdc1[1] sdb1[0]
128384 blocks [2/2] [UU]

unused devices: <none>

I'm heading home now (it's 22:00, and I've been here 16 hours already), but
I figured that I'd post what I have thus far, and perhaps you can tell me
what the problem is.

-Bill
