I have finally to surrender. If anyone thinks on anything we can try, you can contact directly to me or add the information here.
Ok, just to fill in the blanks: was this a regression? Was there a kernel or X or GNOME upgrade before which the system worked fine and after which it broke?
X devs: it looks like there are two sets of symptoms here --- sometimes there are GPU lockups, and other times (e.g., the syslog from 2012-01-22) page table corruption with no obvious trouble before that. Questions:
- is there any simple way to figure out what exactly is causing the regression? E.g., after starting X without accelaration can we explicitly provoke whatever caused trouble?
- is it normal that after a lockup the GPU fails to reset? Even if the GPU lockup itself is not well understood, is that later failure fixable?
