I got this on a fresh install of Lubuntu 15.10 (64 bit).
I checked dmesg and it said to file a bug report here, so I did.
Hope it's useful.

$ uname -r

[ 1867.816864] [drm] GPU HANG: ecode 3:0:0x408460c1, in Xorg [784], reason:
Ring hung, action: reset
[ 1867.816868] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
