would dri cause sporadic freeze with a higher probability of freezing
when/after watching a video (xv) and/or maximizing windows (especially
after with kernel 2.20+) in mergedfb setup ? Could it also trigger NMI
watchdog on an smp box (see this way too often these days on 2.6.17) ?

Also still using a mergedfb setup, I often see a ghost cursor appearing
on the other screen while I'm doing some stuff on a particular area of
the second head. If setup is [Screen 0][Screen 1], the ghost cursor
appears on screen 0 and sticks to the left of the screen while the real
cursor is on screen 1 navigating between about 0 and 500 pixels of the
left border (mergedfb is 2560x1024).

For the moment I've disabled dri and composite extension and the box
seems way more stable even so it appears it stills freezes after
watching a video on screen 1 while this doesn't happen when watching on
screen 0.

I know it's bad to extend mail topic like this but since I think it's
somehow related, I'm jumping on the occasion before trying to fill
proper bug reports. Obviously the problem for me is to have a way to
reproduce these problems with a good accuracy and I couldn't find a way
to get traces of whatever sort so if you have infos, tips and such feel
free to mail me.
