This is what I got wen the problem finally came back (it happens randomly, this time I triggered it by running glxgears, but it can happen for other reasons and none of them triggers it automatically): KERNEL[1246192153.094553] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) KERNEL[1246192153.094734] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) KERNEL[1246192153.095273] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) KERNEL[1246192153.095498] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) KERNEL[1246192153.095665] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) KERNEL[1246192153.095808] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) UDEV [1246192153.096463] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) KERNEL[1246192153.099394] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) UDEV [1246192153.103806] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) UDEV [1246192153.111549] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) UDEV [1246192153.120800] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) UDEV [1246192153.127997] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) UDEV [1246192153.135699] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) UDEV [1246192153.143440] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) UDEV [1246192153.151183] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) UDEV [1246192153.157421] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) UDEV [1246192153.163320] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) UDEV [1246192153.170793] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) UDEV [1246192153.178593] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) So just an endless loop of the same message again and again.
