These were random configs - the size doesnt match an allyesconfig, those are 
way bigger. My above comment related to the first crash, and to my argument 
that all other drivers are fine during bootup - and there's a lot of them.

Thanks. Is there something i can enable to get a better log for you to find 
out where (and why) it's hanging? It's still early during bootup so the box 
is not particularly debuggable - so i'm not sure i can get a task list dump, 
etc., unfortunately.
