Restarting didn't help and I had to reboot. I'm running my own 3.7.1 kernel, so I also installed the 3.7.0 development kernel from Ubuntu (3.7.0-7). And that kernel shows these messages too. With the Ubuntu kernel the graphics corruption is milder. I can continue to work. Sometimes I get a burst of the messages, but I have no clue how it is triggered. Now the strange thing is that I was running my 3.7.1 kernel on Ubuntu precise and I have never seen these messages before. What could be the case is that xorg is doing something new and that is causing the errors. xserver-xorg-video-nouveau precise 1:1.0.2-0ubuntu3 quantal 1:0.0.16+git20111201+b5534a1-1build2 Some more details /var/log/syslog:Jan 4 11:16:42 koli kernel: [ 0.000000] Linux version 3.7.0-7-generic (root@koli) (gcc version 4.7.2 (Ubuntu/Lin /var/log/syslog:Jan 4 11:16:44 koli kernel: [ 18.081288] [drm] Initialized drm 1.1.0 20060810 /var/log/syslog:Jan 4 11:16:45 koli kernel: [ 18.615246] nouveau [ DEVICE][0000:01:00.0] BOOT0 : 0x04b300b1 /var/log/syslog:Jan 4 11:16:45 koli kernel: [ 18.615251] nouveau [ DEVICE][0000:01:00.0] Chipset: G73 (NV4B) /var/log/syslog:Jan 4 11:16:45 koli kernel: [ 18.615254] nouveau [ DEVICE][0000:01:00.0] Family : NV40 /var/log/syslog:Jan 4 11:16:45 koli kernel: [ 18.616802] nouveau [ VBIOS][0000:01:00.0] checking PRAMIN for image... /var/log/syslog:Jan 4 11:16:45 koli kernel: [ 18.655315] nouveau [ VBIOS][0000:01:00.0] ... appears to be valid /var/log/syslog:Jan 4 11:16:45 koli kernel: [ 18.655320] nouveau [ VBIOS][0000:01:00.0] using image from PRAMIN /var/log/syslog:Jan 4 11:16:45 koli kernel: [ 18.655505] nouveau [ VBIOS][0000:01:00.0] BIT signature found /var/log/syslog:Jan 4 11:16:45 koli kernel: [ 18.655509] nouveau [ VBIOS][0000:01:00.0] version 05.73.22.67 /var/log/syslog:Jan 4 11:16:45 koli kernel: [ 18.660805] nouveau [ PFB][0000:01:00.0] RAM type: DDR2 /var/log/syslog:Jan 4 11:16:45 koli kernel: [ 18.660811] nouveau [ PFB][0000:01:00.0] RAM size: 256 MiB -- Kees Bakker
