The central riddle is how mount(8) can fail to make the filesystem available without visibly reporting an error. A question about "mount -v" and its exit value is pending. Maybe one should also look at dmesg output after such a silent failure.
Yes, there are often messages in dmesg which do not appear in the mount output. I don't think the kernel API for mount passes those to the caller. I'd want to see that, and also the filesytem type (which, if mentioned, got lost in this wandering thread).
