If these persist after you fix your crashes, yes.  The 'wd0 bn' field is
the one you should be watching; in this case the first attempt at writing
to block 34576 on wd0 failed, but a subsequent attempt succeeded.  This
would tend to imply that that block is on its way out.

If the numbers show up all over the place (ie. not just one or two blocks)
then the disk itself is dying and should be dumped ASAP.

Note that this problem _could_ be a symptom of your other difficulties.
