Hi,
The conversion to DRM commit helpers (f3c420fe19f8, "drm/vc4: kms: Convert to atomic helpers") introduced a number of issues in corner cases, most of them showing themselves in the form of either a vblank timeout or use-after-free error.
These patches should fix most of them, some of them still being debugged.
