Comment 1 Rodrigo Vivi 2017-10-31 17:15:20 UTC 
This is interesting...

My first question is: Did you recently upgraded the BIOS on this BXT?

But I'm interested because it also happened on happened on drm-intel-fixes for 4.14-rc6 after applying:

dc35b1129cc3 drm/i915: Hold rcu_read_lock when iterating over the radixtree (vma idr)
23e873389d84 drm/i915: Hold rcu_read_lock when iterating over the radixtree (objects)
7c838e2a9be5 drm/i915/edp: read edp display control registers unconditionally
8777b927b92c drm/i915: Do not rely on wm preservation for ILK watermarks
713946d16f45 drm/i915: Cancel the modeset retry work during modeset cleanup


Is this 100% reproducible? I wonder if there is a quick way to bisect between
these 5 patches at least.

Also adding relevant people to cc here in case someone has any idea.

Thanks,
Rodrigo.
Comment 2 Rodrigo Vivi 2017-10-31 17:35:00 UTC 
s/4.14-rc6/4.14-rc7.

I meant that these patches are applied on top of 4.14-rc7 queued for 4.14-rc8.
Comment 3 Jani Saarinen 2017-10-31 17:40:52 UTC 
I think no BIOS update was done, but Tomi to say for sure.

If you check https://intel-gfx-ci.01.org/tree/drm-tip/ click on fi-bxt-dsi on:
https://intel-gfx-ci.01.org/tree/drm-tip/fi-bxt-dsi.html
you will see that this has only happened once since CI_DRM_3218.
Comment 5 Tomi Sarvela 2017-11-01 09:18:55 UTC 
To my knowledge, the BIOS for this machine has not been changed after it was added to the farm. Note that the BIOS version and settings have been handpicked and -tuned to support the DSI panel by Mika Kahola.
