They are crash issues only, in having to deal with the shifting sands of
the underlying kernel.  

In both cases, the problem has always been that assembly-code labels are
stored as text symbols, which is confusing to the backtrace code.  And in
both cases, the new kernel changes interfered with the work-arounds put in
place by the crash utility to handle them.

In any case, it's not a big deal as it's fixable in the crash utility.

Thanks,
