Doc,

   It will take one of the smarter devs to tell you exactly what the error is 
telling you, but it looks to me like your initramfs got 
borked/corrupt/whatever and for some reason it can't determine what modules to 
load because whatever hook or link to the modules.dep file is either not there 
or broken.

   In my case when this happened with 3.4.4-2 and dmraid, I had to boot with 
the 2010.05 install disk due to the latest not having dmraid hooks, then I had 
to manually assemble the dmraid (not your 'md'raid) arrays and manually remake 
the initramfs with 'mkinitcpio -p linux'. This fixed my initramfs corruption. 
(mine wouldn't even boot to the modules.dep point)

   After remaking the image -- all my problems went away. I don't know why I 
experienced this issue for the first time with 3.4.4-2, but I suspect it has 
to do with 'filesystem' and not the kernel. I have seen some weird issues both 
with dmraid and with archroot in the past couple of weeks.

   Like I said, a smarter guy will have to help with the exact message, but 
hopefully a remake of the initramfs will straighten your modules.dep problem out.
