Created attachment 114453 [details] crash dump I noticed a really strange problem. I have an Android Phone connected by USB, a cheap Chinese one which sometime crashes. When the Phone crashes the image on both screens freezes. When I disconnect the Phone, the freeze on my screens is gone. I hat this bug more than three times, so I decided now to fill in this bug report, even it sounds really strange for me. OS is Ubuntu 14.04. CPU/GPU is Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz dmesg output: [ 6454.656894] [drm] stuck on render ring [ 6454.656897] [drm] GPU crash dump saved to /sys/class/drm/card0/error [ 6454.656897] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. [ 6454.656898] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel [ 6454.656899] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. [ 6454.656899] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
