Hi Alan,
I've just been testing the git head v2.6.23-6636-g557ebb7 and there's
still a problem with this.
if I don't mount a disk I start getting timeout messages approximately 1
hour after boot :-
...

On a fresh boot if I mount a cd access it then unmount it, the timeouts
start within about 5 minutes of the unmount
