  There's a minor bug in adosfs/advnops.c that hasn't been fixed yet.  Some
one posted a message about it quite some time ago, and I mentioned it to
Chris Hoopes, but it doesn't appear to have made it into the source.

  The bug is an unintialized variable that is used for the protection mask,
so it's going to do strange things when the permissions are being checked.

  That's extremely unlikely, as it's not a bug to be fixed.

  Since you are compiling your own kernel, change line 711 in
adosfs/advnops.c from:
        error = 0;
to
        error = mask = 0;
and see if that helps.
