Hi,
the last error message seems to come from the following config option:
CONFIG_DRM_FBDEV_OVERALLOC=200
Changing it to the default value fixes the issue:
CONFIG_DRM_FBDEV_OVERALLOC=100
If you enable drm debug (drm.debug=0xff), you get some more info:

Hi,
Sergey Suloev already reported this NULL pointer dereference [1].
Now he was able to provide a Kernel config and i'm able to reproduce
it with a Raspberry Pi 3 (arm64) and Linux 4.19-rc5. It seems like a
invalid config [2] for vc4, but nevertheless the driver shouldn't
crash at boot.
I didn't see that report, thanks for cc'ing me Stefan.
Thanks for the report Sergey.
I've sent a fix:
