Weird - Arch Linux ARM won't start

Hello,
I know that some will think that this is not a forum specialized in Arch Linux ARM, but it is booting Jeff's uBoot and I am having a hard time.
My system is composed of a Seagate Dockstar.
I'm trying to boot from an external USB HDD which has 2 partitions:
- /dev/sda1 which has /boot and is formated as Ext2
- /dev/sda2 which has / and everything else (besides /boot) which is formated as Ext4.

Here's a copy of my environment variables:

Should this be:

usb_root=/dev/sda1
usb_rootfstype=ext2

My two partition set up is all about power outages.
I usually have a lot of power outages at home.
When that occurs more than 3 or 4 times, my dockstar won't boot anymore.
Then I need to take the usb hdd out of the dockstar, plug it into my laptop, run fsck on it and then I can plug it back into my dockstar and it will boot again.
This is a big set back especially because I have a lot of power outages at home.
Then I found out lurking around that having /boot in a separate read-only partition could fix that issue.
At least, that's what I understood.
So, yesterday mrsteveman1 helped me to install ALARM on my dockstar, copying /boot to /dev/sda1 and all other files and folders to /dev/sda2.
Did the necessary arrangements to fstab and set up the environment variables as printed above.
Can see the unit booting up until the kernel loading and then I cannot ping or ssh the unit.
I wish someone would simulate such a working environment just to make sure that it (still) works.
Thanks in advance.
Cheers

After further review it looks to me like it trying to find the /boot/uImage on sda1. You could try just changing "usb_device=0:1" to "usb_device=0:2"

I have a similar problem on my pinkpogo. I have /boot on sda1 and the rootfs on sda2, ext3. I've set
usb_root=/dev/sda2 and
usb_rootfstype=ext3,
but it looks like the archlinux kernel is ignoring the usb_root because when I look at the kernel booting over the serial line I see:

[ 21.337460] Kernel panic - not syncing: VFS: Unable to mount root fs on unkno
wn-block(8,1)

The 8,1 is /dev/sda1, so it looks like the rootfs=/dev/sda2 bootargs is not being sent.

What I did to fix it temporarily was
set usb_custom_params root=/dev/sda2

Then it actually boots for me. Not sure why this works. It could have something to do with usb_set_bootargs (maybe for archlinux the rootfs needs to come after the rootfstype). You'll have to use fw_setenv if you don't have serial access.
