I had come to the same conclusion. I upgraded to the latest drm kernel drivers (DRI cvs) and the message disappeared. It was a mistake to associate it with IO-activity. Shame on me. On the other side, I'm using kernel -ck5, which includes reiser4 and does not suffer from the problem I described. I'm waiting for the next -mm release to see if it gets fixed there too. BTW, thanks to all you people at xorg, you are doing a wonderful job :-) Regards, -- Dr. Francesco Biscani Dipartimento di Astronomia Università di Padova biscani@pd.astro.it
