Looks ok. /dev/sda is the device you're booting from?

What could be worth a try (unless grub devs show up):

* try initramfs-tools >= 0.95.1
* try removing all devices except one disk from the raid1 array
and try booting from the single disk then

I don't know. The bios is set to boot from SAS disk 0 which is **usually**
/dev/sda; however, when my firewire drive is connected, on boot all the drives
are shifted one drive letter.
/dev/sda => /dev/sdb
/dev/sdb => /dev/sdc ... etc

Uhhh? I use this computer on a daily basis! You are going to have to
convince me before I experiment anymore.

For trying a new initramfs-tools, I don't think I will be doing that at all.
For removing all devices from the raid1 array, see the previous paragraph...

Removing the firewire drive when booting doesn't change anything,
right?

I just uploaded initramfs-tools 0.96.1, just upgrade it and give it
a shot. Booting from the single disk isn't necessary therefore,
that would be just another method to isolate the bug.

Correct.

I loaded and booted after the initramfs-tools 0.96.1. The problem persists; I
still have to use the backup image to boot the machine. It has something to
do with grub not being able to read the image; at least this is what a random
error message indicates before the kernel panic previously posted (under
Bug#582177) occurs.
