Created attachment 35849 [details] Kernel log from boot. The issue occurs at 19:02. Hi, First, sorry if I make mistakes, English isn't my native language. I'm experiencing an annoying issue since I use Nouveau driver (which I keep up-to-date). Sometimes, when I'm playing a video, my screen completely freezes. I can still move the cursor (which keeps the same appearance) but I can't do anything else. Ctrl-Alt-Backspace doesn't restart X, and Ctrl-Alt-Fn doesn't bring me to a console. The sound stops too. I have to manually shutdown the computer. This bug occurs whith any player (mplayer, vlc...). It doesn't occur with videos embedded in a Flash plugin. I would say this happens half the time, often during the first seconds. I'm using Debian Sid for amd64. My graphic card is a GeForce 8200. I have RandR enabled and two monitors. I attach my kernel log. The issue occurs at 19:02. These are the most useful lines : May 25 19:02:25 Igloo kernel: [43778.248875] [drm] nouveau 0000:02:00.0: PFIFO_DMA_PUSHER - Ch 2 May 25 19:02:25 Igloo kernel: [43778.250999] [drm] nouveau 0000:02:00.0: PGRAPH_DATA_ERROR - Ch 2/5 Class 0x8397 Mthd 0x0e08 Data 0x00000000:0x3f4c0000 May 25 19:02:25 Igloo kernel: [43778.251006] [drm] nouveau 0000:02:00.0: PGRAPH_DATA_ERROR - INVALID_VALUE
