sounds a little like this bug I'm seeing:

  https://bugzilla.ubuntu.com/show_bug.cgi?id=6108

Except in that case, the mouse is dead too.   Does the caps-lock key
change the little LED, post-hang?  does it happen on a text console?
Also check to see if it happens with laptop-mode inactive, if you're
running that.
