I had the vblank messages in 2.6.25-git17 or so, but they seem gone no. At that time, I also had lockups, mostly when switching back from a vt to X. I was still able to move the mouse, but the rest of the screen just didn't change anymore. SSH login was still possible, so I tried to restart the X server, but that did nothing. Although the X processes were finished, I still had the X surface on my display, what seems rather strange to me. By now situation has improved a bit, as the machine doesn't lockup anymore. But from time to time I still get windows where only the outer frame is shown, the contents of the window is transparent. I have the impression that suspend/hibernation worsens the problems (no proof though). My graphics is a gm965 and I'm using gnome with the new compositing-able metacity used in ubuntu 8.04.
