Nov 6 12:55:59 localhost kernel: [185678.176073] [drm] GMBUS [i915 gmbus vga] timed out, falling back to bit banging on pin 2 I've attached the file, but it won't be of any help. Only additional details I can offer was what I was had open and was doing at the time. I am using XFCE4. Updated all packages no more than a week ago. Running: mysql 5.5, postgresql 9.3, apache httpd 2.4 with php5.5, netbeans, 3 terminal sessions, GIMP, Dropbox, Google Chrome. I had just opened a 90-minute YouTube video to listen to in the background as I worked, as I had done many times in the past. First the video froze, while audio kept going, then the mouse pointer stopped moving, but buttons and links reacted to hovering when I moved it. I changed the page and everything else died as well.
The error state is kept in RAM and so lost when you reboot, if you can reproduce the hang and capture that file before rebooting that will be useful.
The error state is lost on reboot. If you manage to reproduce this and have possibility to ssh into the box, grab the error state before booting and attach into this bug. Thanks in advance.
Created attachment 109518 [details] gpu dump
I was able to reproduce the problem and ssh into the system. I attached the log already. Steps to reproduce: 1) Open Google Chrome 2) Visit www.youtube.com 3) Open a random video, watch the first 10-20 seconds 4) If the problem does not happen, goto 3 (it normally takes 2-5 attempts) relevant dmesg: [40741.804076] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. [40741.804079] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel [40741.804081] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. [40741.804084] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

Also, any chance you could have it rename the old log, instead of overwriting it? That way people wouldn't need a second computer to get the log.
You may do the following: switch to a TTY, log in, and pre-type a command such as: cat /your/dump/file/that/does/not/yet/exist /home/youruser/thedump && reboot Do not type enter, reproduce the problem on the graphical TTY, then switch back and hit enter. Your pc should reboot, and you should be able to have your dump in your home folder.
Another version of gen4 dies on Chrome.
