Just to see if it would progress any, I've let it sit at the 'Building 
databases' stage for about an hour and nothing has happened. It looks 
like when this problem does occur, it's pretty permanent, unlike the 
interrupt storm you are experiencing where it progresses enough for you 
to query the state.

So I'm at a loss ... I've tried recompiling the kernel a few times 
removing options here and there. I can't break into ddb ... it doesn't 
panic and I get as much info out of single user as multi user.

Manuel, if you are reading this (sorry for the cc), I generally don't 
have many problems booting xen (outside of the bootdev/rootdev changes) 
or in the ability to provide data for debugging but I find this really 
odd. Not getting a panic and not being able to break into ddb makes it 
even stranger. Have you any ideas?
