The RRIP stuff is all done in cd9660_vget_internal() under an exclusive

It could be a property of the ISO image. "PX" holds permissions (owner,
etc.). Do you get the same messages w/o the patch with the same ISO image /
CD?

I searched little for this message and found kern/63446 PR interesting comment:

Caused by cd9660_vnops.c rev. 1.77. VOP_READDIR returns bogus
d_fileno, VFS_VGET on this value returns bogus vnode with zeroed attributes.

I think that whatever locking is done is done wrong.
