I get this too, but the point is in the version 1.15.4 the problem was
gone (and I am not sure about earlier versions). I was very pleased about
that, because it used to be annoying having the disc check each time I
booted as the discs were not unmounted. But now the problem is is back!
Surely it must be possible to ascertain what changes have occured between
the versions where the problem went away and between 1.14.4 and 1.14.5
where the problem has come back.

I found that this can be avoided by setting the memory flags of vconsd to
global. (IIRC; I believe I posted a message about that on this list at the
time.) So memory protection does work ok for me now, except it is slow,
and I get occasional freezes. Well actually it is hard to say how the
freezes are coming about, but I definitely NEVER get such freezes with
memory protection off, so memory protection must have something to do with
it.
