I recommend asking about this on freebsd-stable at ... and/or raising a PR
in bugzilla.  If there's any more information you can pull out of your
system, that would probably be helpful -- even if it's a case of taking
a photo of your screen and sticking it on a pasteboard site somewhere.

Hmmm... sym(4) looks like it's fairly elderly, implying the same is
probably true of your hardware.  Is it possible your disk controller is
succumbing to the vagaries of age?
