I don't see the fbdev issue in there, but lots of
kernel: WARNING: CPU: 3 PID: 970 at drivers/gpu/drm/i915/intel_pm.c:3647
skl_update_other_pipe_wm+0x177/0x180 [i915]
kernel: WARN_ON(!wm_changed)
Please do file a separate but for that WARN and mention all steps that lead up
to the freeze, even if just "it freezes at random with no forewarning".
I am going to tentatively close this fbdev one following:
commit e77018f7618960f7ec0e73e63868514ff16f8ddc
Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>>
Date: Tue Jun 21 09:16:55 2016 +0100
drm/i915/fbdev: Flush mode configuration before lastclose
Please do reopen if you can reproduce the fbdev oops on a recent (-nightly)
kernel.</pre>
