Created attachment 108750 [details] The content of /sys/class/drm/card0/error when the GPU crashed When scrolling up and down a google inbox in chromium, my computer display dies. The CPU and network is still available, but the display is completely black. I'm running ubuntu 14.04, fully updated to date from official repositories. The machine is a dell inspiron 1525, with an intel GM965/GL960 display card. The crash is 100% reproducible, so I can test fixes and provide additional information as needed. The syslog message contains the following indicative lines: Nov 1 08:08:41 shacharr-Inspiron-1525 kernel: [35964.804220] [drm] stuck on render ring Nov 1 08:08:41 shacharr-Inspiron-1525 kernel: [35964.804230] [drm] GPU crash dump saved to /sys/class/drm/card0/error Nov 1 08:08:41 shacharr-Inspiron-1525 kernel: [35964.804233] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including u serspace.
