I believe it is nouveau's fault as I found these lines in /var/log/kern.log: Oct 28 18:00:50 jakob-Vostro-1500 kernel: [ 1454.599145] [drm] nouveau 0000:01:00.0: fail ttm_validate Oct 28 18:00:50 jakob-Vostro-1500 kernel: [ 1454.599150] [drm] nouveau 0000:01:00.0: validate vram_list Oct 28 18:00:50 jakob-Vostro-1500 kernel: [ 1454.599204] [drm] nouveau 0000:01:00.0: validate: -12 The crashes appear to be nondeterministic: Most of the time, when I boot the system with external displays plugged into the VGA port, something crashes. In the worst cases the whole system crashes and only SysRq keys are working. At other times I'm still able to reach the terminal via ctrl-alt-f1. Even if the system survived, the window manager often later on hangs and displays false colors and sometimes recovers. The log files automatically attached by apport should document the latter error symptom. I'd be happy to supply more information if you can give me hints how to gather them.
