Ah, yes.  I should probably find a way to code that rather than relying 
on the user to put it on the command line.

That's a pity; I was hoping those problems would be behind us...  Do you 
have any log messages relating to them?

The USB lockdep error isn't terribly worrying if the machine doesn't 
actually lock up.  I'm still working on a good way to fix that one.

The NULL pointer dereferences are much more of a worry, and a bit 
random.  Looks like the stack pointer has got trashed or something, so 
its not giving any useful information.  Do you know what was going on 
before then?
