Description Matthias 2017-07-19 06:09:54 UTC
[ 6899.102492] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[ 6899.102493] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[ 6899.102494] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[ 6899.102495] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

Oh no it is not. That file is never empty, at the minimum it says "No error state collected".

Hello Matthias, 
Could you please add HW and SW information and attach dmesg with drm.debug=0xe parameter on grub from boot, also is there any steps to reproduce it?
Thanks

Hello again,
I noticed your using a docking station. It seems that some features for this devices had been included on 4.12 and up, https://www.kernel.org/, could you please try with the latest kernel or drm-tip, https://cgit.freedesktop.org/drm-tip, thanks.

+1 for encountering this bug whilst using 2 HD monitors with a Dell docking station.
