Yes, I rebased drm-misc-next on top of vmwgfx-next and found the culprit
38b6441e "drm/atomic-helper: Remove the backoff hack from set_config.."
Reverting first 1fa4da04 and then
fixes the problem.
Also, when testing the tip of drm-misc-next (with the non-atomic vmwgfx)
there appeared to be warnings about a non-NULL
dev->mode_config.acquire_ctx. I'll see if I can reproduce those, but
perhaps removing the line
dev->mode_config.acquire_ctx = &ctx
is part of the problem.
