Hello Graeme, If it is to any help, I have the exact same problem. I didn't know though that the kernel error msgs (exactly same for me) were related to the spin down. I'm also looking for ways to prevent the spin downs.. I'm using 2.2.7-STABLE and the hd is a IBM Deskstar 8gb.. (the other two IDE hd's don't spin down). Best Regards, Markus Holmberg.
