Once you get any kernel to successfully assemble the array, any other 
kernel/mdadm should be able to as well.

After 2 days pulling my hair out, the answer was a simple as popping in the
Arch install CD and rebooting!!

After it booted, I checked cat /proc/mdstat and /dev/md1  (md125) on Arch is
active and re-syncing. Perfect.

That was a whole lot of work to find out that it was an old mdadm causing all
the problems -- live and learn...

Perhaps we should add "get the latest release of mdadm" to the Raid Recovery
page with the explanation that sometimes older versions of mdadm just do not
know how to handle simple issues that arise, such as differing Event counts.
Using the latest mdadm can solve those problems immediately.

Glad that it is now working for you!

Isn't "Make sure you have latest release" always the second thing to check
(after checking that you are actually using the command properly:-)??

But yes, it doesn't hurt to add it to a wiki page somewhere.
