Created attachment 167921 [details] Output of lshw I upgraded to the 3.19.0 kernel several days ago on my Ubuntu 14.04.2 LTS system running on a Dell Optiplex 780 with 4Gb ram. Since then quite often I'll see this in my syslog: Feb 22 18:00:46 localhost kernel: [ 9088.033815] [drm:intel_crtc_cursor_set_obj] cursor off Feb 22 18:00:46 localhost kernel: [ 9088.033821] [drm:g4x_check_srwm] SR watermark: display plane 92, cursor 2 Feb 22 18:00:46 localhost kernel: [ 9088.033822] [drm:g4x_check_srwm] display watermark is too large(92/63), disabling Feb 22 18:00:46 localhost kernel: [ 9088.033824] [drm:intel_set_memory_cxsr] memory self-refresh is disabled Feb 22 18:00:46 localhost kernel: [ 9088.033826] [drm:g4x_update_wm] Setting FIFO watermarks - A: plane=40, cursor=2, B: plane=2, cursor=2, SR: plane=0, cursor=0 Quite often I'll also come to a black screen with only the mouse cursor. The cursor will move however I can't get back to the desktop. Today when this happened I was able to blindly CTRL>ALT>F1, login and run sudo reboot which rebooted the system. I really don't know if any of the above has anything to do with the lockups but if there are any other log items I need to look for I'll gladly do it. I have hourly log snippets for months. I'm also attaching the output of lshw and dmidecode in case it helps
