Does the > problem only occur for one of them? Miles isn't alone, I also get 'trying to get vblank count for disabled pipe 0' (GM965). vblank interrupts were previously not working for me, but they are now. I'm not sure what's changed. > > Do you have any GL apps running when this happens? > For me, this happens every time a GL app is run. I'm also getting occasional lockups. Often it's the window manager (metacity) that locks up when attempting to move a window, restarting the window manager unlocks X but attempting to move a window again results in another lockup. When it's locked up the pointer moves and vt switching works but nothing else. Other times I've had a hard lockup that required a hard reboot, this happens less frequently.
