Hi. Thanks for the help. Reverting kernel commit 5727dcfd8486399c40e39d2c08fe36fedab29d99 ("fbdev: Make registered_fb[] private to fbmem.c") and building clean (“make clean”) to ensure conftest is updated fixes it. Issue is in kernel-open/nvidia/nv-platform.c, where nvidia forcefully disables the clocks used by the framebuffer driver. Upstream removed the variable they used to check for (to see if a framebuffer has been registered?) before disabling the clocks.
