The ..config for my linux kernel

If I hibernate from the console, thaw, and switch between the console
and X, the gpu hangs itself. The machine becomes unresponsive except
for the power button.

    21:12:16  kernel: [drm] GPU HANG: ecode 8:0:0x0f71ffff, in Xorg [2047], reason: Hang on render ring, action: reset
    21:12:16  kernel: [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
    21:12:16  kernel: [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
    21:12:16  kernel: [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
    21:12:16  kernel: [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

    drm/i915/cmdparser: Add the TIMESTAMP register for the other

as the first bad commit, i.e with a gpu hang after hibernation. This
sseems spurious, reverting this commit didnt not help.

This is a Lenoveo T450s with Broadwell-U Integrated Graphics. I attach
my .config and /sys/class/drm/card0/error.
