Pardon me, but how do I break into the debugger ? :)
I know, if I'm using -CURRENT I should know how to do it... could you 
point me at the right direction anyway ? :-)

Even if I could break into debugger, I would need to get a serial 
console working, otherwise a stack trace could be quite hard to get. I 
don't think I want to type this by hand...
