I think that it's not expected for CURRENT to be very stable and it's  
more less expected that you are able to follow current because sooner  
or later  you'll have problems like the one you have. I suggest you  
run STABLE.

That aside, hardlocks are hard to debug, specially while on X. My  
first try would be to remove drivers one by one.
