stacktrace shouldn't post non kernel values, unless there's a frame
pointer that isn't handled by kallsyms.

As for the other two, we could probably force a failure, like:

 # echo 'hist:keys=hrtimer.sym' > \
     events/timer/hrtimer_start/trigger
 # cat events/timer/hrtimer_start/hist

And then just add sym-offset too.

Can you try the above.
