I'm sure you would :)

This is not a problem that is happening to me (I am not skull), and I
of course do not have any proof that this is a software bug, let alone
a patch.  I just found it strange that a hardware problem would cause
"BBBB" to be found where some sort of TDB magic value was expected.
You, of course, have infinitely more experience with this sort of
thing than I have.  I just thought I'd ask.
