Another thing that only strikes me now that I'm actually counting them: I have 
_exactly_ 24 of those messages per minute. At any moment, at any time, idle 
or not. (Although a PVR is never really 'idle', but nevertheless)
(well, not really _every_ time, but out of ten samples nine were 24 and only 
one was 36)

And this one may be particularly interesting:

Jan  9 02:47:19 dozer kernel: raid5: switching cache buffer size, 512 --> 4096
Jan  9 02:47:24 dozer kernel: raid5: switching cache buffer size, 0 --> 4096
Jan  9 02:47:24 dozer kernel: raid5: switching cache buffer size, 4096 --> 512

Switching from buffer size 0 ?  Wtf ?

Another thing to note is that my switches are between 4096 and 512, not 
between 4k and 1k as Neil's reply would indicate being normal. But I don't 
consider this bit really important.
