Well there are two problems here

1) Kernel warning: drm_irq.c:1326 drm_wait_one_vblank+0x191/0x1a0 [drm]().....This is probably due to https://github.com/torvalds/linux/commit/74c090b1bdc57b1c9f1361908cca5a3d8a80fb08 as stated in https://bugs.freedesktop.org/show_bug.cgi?id=93782

This can be fixed in by appending "video=SVIDEO-1:d" to kernel boot command.

2) It's this bug which still exists in v4.10-rc7. The possible cause is :

ea0000f0d369a59c2086fe9c489e0a2a86e080ba - drm/i915: Roll out the helper nonblock tracking.

A patch (https://patchwork.freedesktop.org/patch/128918/) was proposed to disable it But according to @Jim Rees's comment on the patch they are not going to push it 4.9 and it may not land for 4.10 either.

So that means I have to manually apply the patch and see if it gets fixed.
