For further information I have had the same problem mounting a sony walkman NWZA818, and also the same problem mounting it in SUse Linux 11.0 (kernel 2.6.25.18-0.2-pae) but it works fine in 11.1 (kernel 2.6.27.7-9-pae)
My Ubuntu machine is now running 8.10 (kernel 2.6.27-8-generic) and the sony mounts fine.
I am fascinated by the idea that the kernel team doesn't need to know about kernel bugs, BTW.
