My best guess is that you are facing two separate bugs here.
Crash #1 is somehow related to CRTCs and might even be cause by the
atomic-helper change you noted below.
Crash #2 is caused because vmw_bo_create_and_populate() tries to
manually populate a BO object instead of relying on TTM to do it when
necessary. This indeed doesn't work any more because of "drm/ttm: make
TT creation purely optional v3".
Question is why vmwgfx is doing this?
Not really sure unfortunately, it's possible vmwgfx is doing it because
ttm lacked some capabilities at some point?
I think so as well, yes.
Trying to figure this one out...
Problem is that what vmwgfx is doing here is questionable at best.
By definition BOs in the SYSTEM domain are not accessible by the GPU,
even if it is a virtual one.
And what vmwgfx does is allocating one in the SYSTEM domain as not
evictable and then bypassing TTM in filling and mapping it to the GPU.
That doesn't really makes sense to me, why shouldn't that BO be put in
the GTT domain then in the first place?
Christian.

Hello.
Commit 2ddef17678bc2ea1 ("drm/ttm: make TT creation purely optional
v3") broke vmwgfx .
At first I suspected it is "drm/atomic-helper: reset vblank on crtc
reset" or around that,
but bisection said it is not. I have no idea what is going on. Please
have a look.
