I had come to the same conclusion. I upgraded to the latest drm kernel driv=
ers=20
(DRI cvs) and the message disappeared. It was a mistake to associate it wit=
h=20
IO-activity. Shame on me.

On the other side, I'm using kernel -ck5, which includes reiser4 and does n=
ot=20
suffer from the problem I described. I'm waiting for the next -mm release t=
o=20
see if it gets fixed there too.

BTW, thanks to all you people at xorg, you are doing a wonderful job :-)
