You also want to take each stack value that is between _text and _end 
labels and call print_symbol() on it. That will give you a better 
impression of the backtrace quickly. If you also print the stack delta 
between each value that you pass to print_symbol() you'll also see 
which are the stack frames that are really troublesome.
The few stack frames you looked at already look quite innocent. They 
don't take up much stack space. OTOH it is somewhat weird to be doing 
writable pagetable work that far down the stack. It'll be interesting 
to see what was going on to cause writable pagetable state to be 
flushed.
